I am pursuing a PhD in mathematics at Drexel university in Philadelphia, PA. I started my Teaching assistantship in fall 2013. As of now, I am not sure where my interests lie, though I am leaning towards something along the lines of matrix analysis.

I'm here because I enjoy being a part of the MSE community, and because whether you're asking or answering, you can never get enough practice with math problems.

Some answers I had fun putting together:

I was wondering where you signature sign-off was :) Always a fan of your contributions here!

comment Proving antisymmetry within matrices
@Irwin how about starting with $(AA)^T$, and seeing where you can go from there?

comment Demonstrate that p ↔ (p ↔ q) ⇔ q
No need to apologize. Glad to help.

comment Proving antisymmetry within matrices
Well, that's what you have to prove. That statement is precisely what is meant by the statement "$A^2$ is a symmetric matrix".

comment Proving antisymmetry within matrices
I don't understand the question as you've asked it. Do you mean to ask "is $A^2 = (AA)^T$?"

@Thursday I would assume that OP has a vested interest in the completeness of the answer provided

comment Symmetric and Skew Symmetric Matrices
Technically, the $0$ matrix is a skew symmetric matrix that defies this statement

What are your thoughts on the problem? What have you tried? What ideas come to mind?

@DanielFischer of course... that was bothering me, thank you

Why isn't $a \in E'$?
