Lattice

[@_PAYALGAIKWAD]

all videos are arranged so well in a proper sequence

[@trusttheprocess4775]

Fantastic videos. These videos are alone going to help me pass maths this semester.

[@nins1709]

Thank you so much. Your one lecture clears all my doubts about the lattice topic

[@benalbritton]

FYI, you don't call the symbol for the empty set "phi". Phi is a greek letter that looks a little similar to the symbol for the empty set, but mathematicians are not using the greek letter phi in this case, it is just it's own symbol that denotes the empty set.

[@AkamiChannel]

Yeah that was surprising for such a well-presented and informative video to make this error

[@pranavnyavanandi9710]

Please list the related playlist in the video description as well, it makes it much easier to navigate.

[@madapanameena1320]

From figure (a) Consider the incomparable pair (d,g) GLB(d,g)=f LUB(d,g)=¢( null set) So, this is not lattice. I have doubt .. please clarify that.

[@adityaralhan1154]

Lub of d and g is g

[@marcusmors8485]

Thank you, it was easy to understand and you set the previous knowledge requirements from the start.

You are a life saviour sir🔥💯💥

[@ankitpanwar5032]

Thank you❤❤ neso academy, I grateful to for my sessional exams

[@rishabhm456]

Hi five bro 🤜

[@ambikas4905]

Well explained,with more examples,there is no doubt n understand

[@barlog6679]

wouldn't b GLB(f,g) = e?

[@agnidebmukherjee9756]

Yes true..

[@agnidebmukherjee9756]

@@adityanprakash1281 not at all

[@csbytes137]

Same doubt

[@barlog6679]

i figured it out, the elements that can be GLB in (f,g) are e and b. Since you cannnot determine whether e is greater than b or b is greater than e due to the lack of relationship between e and b, there is no GLB. The same logic applies to determine the GLB and LUB of other pair of elements.

[@its_ayush7286]

@@barlog6679 thank you for pointing out my same question and also for giving the answer of it. That is something that i didn't know.

[@chiragmehta2955]

sir your voice so soothing ..after hearing that it makes maths a very easy subject. thank u for ur hardwork.

[@kashmirking2446]

Thank u so much sir.....all videos are in proper sequences

[@praveenkumarchettiyar2695]

Thankyou sir you rescued me a day before exam 😊😅

[@jordynbell02]

This video is absolutely amazing!

[@user-vk9vx8uk2p]

this guy is an amazing teacher omg

[@y.8901]

Hello, at 7:25 can we say that the lower bounds of (f,g) are b,e,c,a but since b and e are not comparable -> No upper bound ?

[@doesnotexist8873]

yes

[@rajeshprajapati6662]

Upper bound of (f,g) is h. There is no lower bound for (f,g). You should have written "No Lower Bound".

[@prithwihegde349]

​@@rajeshprajapati6662hey y e can't be considered as GLB? Please could you explain...

[@_PAYALGAIKWAD]

thanks a lot sir..Your videos are so easy to understand and organised...

[@mahendrakergaurav5867]

thanks man,apppreciate your work

[@zeusbgmi6476]

This is somewhere excellence is found!

[@yeongwooh4921]

GLB(f,g) for all pair isn't defined, thus the set is empty. since the two preceding lower bounds are incomparable, we can't define greatest lower bound.

[@wrath2801]

bhai tu IIT ka hai?

[@suhankrishna4567]

i will pass because of you. god bless you!

[@saiyedasiddika3974]

It’s really helpful

[@teneplays]

8:45 example 3 was the same as in my notebook

[@Akshay_pratap_singh_007]

Very well explanation Sir !!

[@egehanyildiz]

sir in example (b) isnt GLB of f and g is a? By following the path downwards we can find a lowerbound

[@rajeshprajapati6662]

Lower bound of (f,g) - abce Let's check for GLB : a - All elements of LB related to a ? No [Using Hasse Diagram] b - All elements of LB related to b ? No [Using Hasse Diagram] c - All elements of LB related to c ? Obviously No [Using Hasse Diagram] e - All elements of LB related to e ? Obviously No [Using Hasse Diagram] So, GLB = Phi

thanks man!@@rajeshprajapati6662

[@sidrahwaris7885]

thank u so muchhhh very helpfullll!!!!!!!

[@DuongNguyen-en1pi]

6:12, example 2 (a), what is the GLB and LUB of pair (d and g)?

[@enes5345]

GLB d and LUB g

[@marah8158]

@@enes5345 couldn't be like this? GLB is f LUB is ø how GLB is d when they first meet in f?

[@likithgannarapu8454]

at 8:15 in example(c) why didn't you consider (b,c) as incomparable????

[@rajeshprajapati6662]

You can consider it and you will find that unrelated pair (b,c) has GLB = a and LUB = g.

[@satyamtiwari331]

fantastic explanation

[@osamansr5281]

what does the "rank" of a lattice mean? what's a "rank-1" lattice?

[@isai5813]

Please add python and Dynamic programming courses too

[@bbmathematics224]

Excellent method..❤

[@arunsuresh8547]

In fig (c) why don't you consider f,e and d,c as incomparable pairs ?

[@engineerguruji2]

Thanks so much

[@brainexercise1234]

Nice explanation

[@pahadiraishgamer1777]

Very helpfull

Amazing !🎉🎉🎉🎉

Good morning every one

nice expalined properly

Way better than nptel

[@shivanikj3047]

Thank you 😃

[@leonthethird7494]

You're a legend

[@Kuldeepsingh.]

great video sir

[@kasiiragavarapu673]

At 6:17 why don't we consider (g, d) to check either they have glb and lup

[@doesnotexist8873]

because d is related to g through transitive property

[@lloydmoore6507]

Doesn't 3 also divide 12?

[@nehakhanolkar3861]

Can someone please explain what do we mean by 'incomparable elements '.

[@nileshmishra5482]

It means if neither aRb nor bRa..

[@parmeshwariswami3530]
