Cute fingers.
Thanks!
What are you studying? What are you researching? What are you thinking about?
OP is thinking about starting K-theory to see a connection between rings and topology.
Starting exams soon so I don't have much time to do some of my own stuff but I was reading through a book on Lie groups last night.
Rather interesting for those in undergraduate studies, you can take the exponential of a matrix A in an obvious way, setting:
[math] exp(A) = \sum_{k=0}^\infty \frac{A^k}{k!} [\math]
It's rather useful, especially for solving DEs with matrices.
I'm studying linear algebra and it's kicking my ass. Guess I was a brainlet all along.
Who isn't?
LA is also kicking my ass
>at least I've got stats down
trying to get a handle on clifford algebras and find some applications of lifting modular forms
Reading on motivic integration and kinda getting my ass kicked
