Sir, jab one one k baat Kar rahe the 3:48 par, toh apne bola domain( x1, x2) codomain(x'1, x'2) Mein domain k dono element codomain k x'2 Mein join ho gaye. But we know that In one to one or injective we can't have many to one. Isn't it?

[@ishikasharma6864]

It was a time when i possessed keen interest in mathematics but now i feel that opting maths in graduation is my biggest flex 😢 Its all on the basis of assumptions and theories... Missing the conceptual and calculating factor in maths now

[@simransaini4248]

Yeah same dude :( I'm also feeling low.

[@yuckertv2701]

It is called "PURE MATHEMATICS" for a reason 😅

[@Captain.Price33]

12 maths 🫡 Bsc maths🤢💀

[@evizgamer]

Its just about teachers, In schools teachers used to teach everything and every questions thoroughly but in most colleges and universities teachers doesn't pay much attention towards students. They just complete their lecture without any concern about students whether they understand anything or not.

[@sumanverma864]

Sir apke videos se mujhe kafi help mili h.... Ap content bhi provide karte ho..... Thanks a lot

Sir I have one question.... Automorphism of Dn is isomorphic to which group ?? (Here Dn is dihedral group). I have only idea of its order.... Order of Aut(Dn) is n × phi(n).

[@43-nidhipandey81]

Thank you...sir🙏

[@UttamKumar-jz8oj]

Wonderful sir

[@geepaspas3221]

sir , in the example 1 how do we understand it is to prove automorphism?

[@ayushkumarsingh2537]

[@ayushkumarsingh2537]

Iska mean x1 and x2 two different elements na hokar 1 hi hai. Isliye hi one-one proof karne ke liye pehale f(x1)=f(x2) let karte hai and baad me ye dikhate hai ki x1 and x2 different nhi h balki x1=x2 hai. Isliye inki image same thi.

[@dumeshmeher9291]

Nice 😊😊

[@himanibagri7217]

Sir , what is meaning of onto itself and into itself

[@himanibagri7217]

Plz reply sir

[@yuvrajvaish1836]

Let G be a group of integers under addition. Is the map f:G→G defined by f(x) = 2x, an automorphism of G?

[@ayushkumarsingh2537]

I think that it is not an automorphism. Because f(x) is not onto in this question.

[@pramodprajapati9556]

Thanks sr ji

[@bushrahabib3391]

Sir is there any lecture on centralizer and normalizer ?

[@Zpathan-fo8ym]

Sir differential geometry and manifold ke playlist bana diye. Pls

[@AakankshaYouthsPower]

Very nice lacture sir

[@bismayprakashlenka8655]

Why should we take gof sir on 12.07 minute

[@ayushkumarsingh2537]

To show closure property

[@teerthendra]

Sir i have a question, homomorphism prove krte par jb hum (x1x2)^-1 ko kholte h toh x2^-1 pehle kyu aata hai or x1^-1 bad me ??

[@ankitgoyal4415]

Wronskian equ p vido bnae

[@ratneshsoni4431]

Sir 12:05 pe gof wala concept clear ni hua

[@ayushkumarsingh2537]

Agar two functions one-one and onto hai to unka composition bhi one-one and onto hota hai, aur ye sir closure property dikhane ke liye kar rhe hai.

[@kumkumkundu5324]

Sir inner automorphism video nehi hai kya??

[@mathsloversjn3453]

V nice explain sir

Where is Inner- external Automorphism sir?
