Timestamps and Summary of Lecture 1: Basic Banach Space Theory 0:00 - Motivation and Introduction Functional analysis works with vector spaces that are sometimes infinite-dimensional, using the techniques of analysis to study their structure & functions defined on them. Besides existing as a pure mathematical discipline, it finds applications in partial differential equations and physics. 5:27 - Review of Vector Spaces Vector spaces are defined over a field (here, R or C) and are closed under addition and scalar multiplication. Every vector space has a basis, or a maximal spanning set; its dimension is the cardinality of any basis (this is well-defined). e.g. Finite-dimensional vector spaces over R: R^n (n-fold Cartesian product) 13:46 - An Infinite-Dimensional Vector Space The set of continuous functions from [0, 1] to the complex numbers forms a vector space (sum, multiple of any elements are still in the VS). But the countably infinite set {1, x, x^2,...} is linearly independent in C([0, 1]). 16:26 - Norms To perform analysis, we require a concrete notion of "proximity" or "size" on our spaces. A norm assigns to each vector in a vector space some nonnegative real number; as a map it is positive semidefinite, homogeneous, and satisfies the triangle inequality. A seminorm is similar to (but weaker than) a norm; it satisfies the latter two conditions but is not necessarily definite. A vector space endowed with a norm is a normed vector space: these are central objects of study in functional analysis. 21:15 - Metric Spaces A metric on a set provides a notion of distance between its points. It is an identity-indiscernible, symmetric, and triangle inequality-satisfying function; a space with such a distance function is called a metric space (has the metric topology) 23:08 - Norms Induce Metrics Given a norm on a vector space, it induces a metric in the natural way. This allows us to talk about ideas like convergence, completeness, etc. with regards to normed vector spaces. 26:11 - Examples of Norms (and NVS) Euclidean norm on R^n, C^n provide us with the most familiar notion of distance. We can consider more broadly the family of norms called p-norms, of which the Euclidean norm is a special case (taking p = 2). When p = ∞ we consider the norm that picks out the maximal component of a vector in n-space. 32:45 - The Space C_∞{X} From a metric space X we consider the space C_∞{X} of all continuous, bounded functions from X to the complex numbers. This indeed forms a vector space - on it, we can introduce the supremum norm that measures the maximal value a function takes. This turns C_∞(X) into a normed vector space. If we take X to be some compact interval like [0, 1], the boundedness of continuous functions are automatic. 39:24 - The Supremum Norm and Uniform Convergence When asking what convergence in this metric means for functions in C_∞(X), we find it translates to uniform convergence in the familiar sense from real analysis. 42:20 - l^p-Spaces The l^p spaces consist of p-summable sequences. When p = 2, these are square-summable, etc. and these are all defined to be the sequences on which the respective p-norms resolve finitely. 46:38 - Banach Spaces We are interested in special cases of normed vector spaces that mimic the situation/structure in Euclidean spaces, namely, their completeness. We have seen that norms (on vector spaces) give rise to metrics, with respect to which we make sense of convergence of sequences. Cauchy sequences are those whose terms tend arbitrarily close; every convergent sequence is Cauchy, but the converse doesn't necessarily hold (the rationals have many "holes": one can construct a sequence of rationals that close in on sqrt(2) but can't converge to it in Q). Spaces for which the converse does hold, i.e. Cauchy sequences converge, are complete with respect to that given metric. Banach spaces are normed vector spaces that are complete with respect to the metric induced by the norm. 49:52 - Examples of Banach Spaces R^n, C^n are Banach spaces with respect to any of the aforementioned p-norms. These provide relatively trivial examples, but foundational ones. 50:39 - C_∞(X) is Banach A useful nontrivial example - the normed vector space of continuous, bounded functions X -> C actually forms a Banach space with respect to the supremum metric. The process of showing that it is a Banach space amounts to exhibiting completeness, and is instructive in demonstrating the general procedure for showing that a space is Banach: first take a Cauchy sequence & come up with a candidate for its limit, then show that this proposed limit lies in the space, and finally show that the convergence does occur.

That's so great! I feel like if getting into grad school at MIT is something you really want to do, then just go ahead and do it and don't let anyone else tell you otherwise! Grad school admissions are *extremely* competitive and you need to have a well rounded profile in order to have a chance to get into any of the programs. Some of these requirements include (disclaimer: this list is by no means comprehensive) good grades, relevant research experience and/or publications and strong recommendation letters from supervisors that can vouch for the quality of research work you have done. Some universities also require you to take a GRE and an English language test. The latter only really applies to you if you come from a country that does not speak English as a first language or if your bachelors/masters degree was not in English. To my knowledge, most PhD positions are fully/partially funded and may require you to also do some TA work in addition to your research. Depending on the school, you may have to pay a fee to send in your application. Good luck and I really hope you find the courage and motivation to go through with this!

Around 1:02:00 , the instructor mentions that C is complete , meaning that for all x belongs to X, u(x) = lim u_n(x). What i got confused is that he mentioned that it has a point wise limit(space of continuous bounded functions), however, this would mean given an x, and epsilon, we can find an N, such that u_n(x) converges to u(x). But by completeness of C, it says for every x , un(x) has a limit( isnt this uniform convergence in C)? and if so, doesnt that show uniform convergence in set of bounded continuous functions? Im confused
@oreo-sy2rc2 жыл бұрын
I‘m not sure I fully understood your question, but add my thoughts here: - complete space here means that a sequence of u_n belonging to X has a limit function which also belongs to X - uniform convergence is defined as there exists an N such that for all x: |u_n(x)-u(x)| < epsilon. So you choose an N for all x, where with pointwise you can choose an N for all x seperately. Therefore uniform is stronger.
@oreo-sy2rc2 жыл бұрын
Okay, I’m also confused. Since u(x) is bounded and has complete domain, its compact. Now the functions are continuous(?), therefore uniform continuous?😅
@witness6347 Жыл бұрын

Anyone knows why {fn=x^n } is linearly independent ?
@akrishna17292 жыл бұрын
Recall that linear independence can be formulated as "no nontrivial relations between a set of vectors" in the sense that any linear combination, say, c_{a_1}*v_{a_1} + ... + c_{a_n}*v{a_n} + ... = 0 implies that each field scalar c_{a_i} = 0. Here we consider the set {1, x, x^2,...}: a countably infinite set consisting of all elements of the form x^n. Suppose we have some nontrivial relation, i.e. c_0(1) + c_1(x) + c_2(x^2) + ... = 0. This forces all of the c_i to be zero, because intuitively, terms of different degree "cannot cancel each other out". As a slightly more tractable example, you can consider finitely many of these terms in a polynomial: if we have ax^2 + bx + c = 0, it's not possible to configure the purely scalar coefficients in a way that allows for this to hold unless a = b = c = 0. Because we've shown that the set {x^n}_{n >= 0}, considered as continuous & bounded functions [0, 1] -> C are linearly independent, it follows that C([0, 1]) cannot have any basis of finite cardinality; hence it is an infinite-dimensional vector space over R or C.

Abstract A growing lattice with a label system of growth in every direction from the centre to infinity whole numbers for measuring size in connection to the size of the lattice label to size and size of the knot so that you can solve a measure from the knot size and size from the label in three dimensions to help solve Euler Brick problem? remember the difference between a label and a size. I will show each three slices of the lattice. slice one centre is 0L0 this is the middle of space x,y,z 0L0 is a label and it has size as well its size is the knot size. L is not just a label knot it has size as well. rule for this lattice A=B pick size of gaps in lattice 20mm pick size of knots L in my lattice is a squares diaginal = 10mm example ----------------------------------------------------------------------------------- example of lattice slice 0 centre 0L0 and centre of lattice 2L0 2L0 2L0 2L0 2L0 1L0 1L0 1L0 1L0 1L0 0L0 0L0 (0L0) 0L0 0L0 -1L0 -1L0 -1L0 -1L0 -1L0 -2L0 -2L0 -2L0 -2L0 -2L0 slice 1 centre 0L1 but not centre of whole lattice 2L1 2L1 2L1 2L1 2L1 1L1 1L1 1L1 1L1 1L1 0L1 0L1 (0L1) 0L1 0L1 -1L1 -1L1 -1L1 -1L1 -1L1 -2L1 -2L1 -2L1 -2L1 -2L1 slice -1 centre 0L-1 but not centre of whole lattice 2L-1 2L-1 2L-1 2L-1 2L-1 1L-1 1L-1 1L-1 1L-1 1L-1 0L-1 0L-1 (0L-1) 0L-1 0L-1 -1L-1 -1L-1 -1L-1 -1L-1 -1L-1 -2L-1 -2L-1 -2L-1 -2L-1 -2L-1 ------------------------------------------------------------------------------------ so a point on the lattice example = 0L0 so the lattice is infinite in every way so a line will look like this. example y = 0L0 + 0L0 + 0L0 = 20mm*3 = y this line on the lattice so a 60mm line. example x = 0L0 + 1L0 + -1L0 = 20mm*3 = x this on the lattice so a 60mm line. the hard point is a diagonal line example = 0L0 + -1L0 + 1L0 + (Knot=1 whole and 2 halves of a knot) so 60mm because A=B so (0L0 + -1L0 + 1L0) = 60mm + knots now a square example = 1L0 1L0 0L0 0L0 example = 1L0 1L0 1L0 0L0 0L0 0L0 -1L0 -1LO -1L0 now a cube 1L1 1L1 1L1 1L0 1L0 1L0 1L-1 1L-1 1L-1 0L1 0L1 0L1 0L0 0L0 0L0 0L-1 0L-1 0L-1 -1L1 -1L1 -1L1 -1L0 -1LO -1L0 -1L-1 -1L-1 -1L-1 By Aaron Cattell

Yeah nah. A lot of students still prefer being walked through the contents and that's what Professor Rodriguez is doing.
