Age: 28

Currently interested in Schur functions, key Polynomials and semistandard Young tableaux and misc. related representation theory and combinatorics.

Phd thesis defended 2013, titled Combinatorial Methods in Complex Analysis.

I keep an eye out for interesting results related to complex dynamics, computability, and computer-assisted research. I use Mathematica extensively in my research. My other main programming languages are Java, LaTeX, PHP, C, etc.

Oh, and I like generative art.

@Szabolcs: Well, they CAN both be uniformly distributed and equal, taking $u_i=v_{\pi(i)}$, for some permutation $\pi$, but then they are of course not independent.

comment Can one make high-level proofs about chess positions?
I think humans are very good at finding plausible explanations for a pattern that has already been observed. People even tend to motivate why they choose 'x' on a survey, even though the tester changed the answer from 'y' to 'x'! There are so many things in society that can be explained by simple-sounding things and which are correct, but some things are also plain wrong.

comment How can a new PhD Student objectively evaluate how well they are doing?
Number of papers written + number of years left. Larger number is better.

comment Fast Symbolic Linear Algebra CAS?
What do you mean symbolic and linear algebra? So, you want to do gaussian elimination, but with some unknown entries?

comment Polynomials with the same values set on the unit circle
Is it possible to prove it in the special case when the images $P(S)$ and $Q(S)$ are a non-intersecting curves?

Ah, they agree as SETS, my mistake.

comment Will the Ph.D. stipend be enough to support my parents?
You might consider doing some private tutoring - 3 hours of tutoring a week might be enough to cover the $400.
