Jan 31	comment	Jordan form and its elements Thanks! You're right! I do curious how you pick $P$ and the inverse of it.

Jan 30	comment	Ring theorem and isomorphic @Andreas I take your steps, and I did my proof! Thanks a lot!

Jan 12	comment	Minimal polynomial and Cayley hamiliton theorem Thanks! So it is not related to minimal polynomial solution, is it?

Jan 11	comment	Minimal polynomial and Cayley hamiliton theorem Thanks a lot! But how come the condition A^3+A+I_n = 0 will not affect the result gained by the brute force? And why can't I use brute force to solve the problem 2?

Oct 27	accepted	Three exercises related to the pigeonhole principle
Oct 27	comment	Three exercises related to the pigeonhole principle @BrianM.Scott: No, I didn't type that can't wrong. I thought the sum should be limit between 1 and 69 since 1 is the smallest postitive integer. Thus the 62 possible subsets will not be able to cover the range of the sum. So I think it can't be proved by pigeonhole principle.
