I am a PhD student at TU Delft, working in applied probability and stochastic optimal control. My current focus is on approximate model-checking of stochastic systems via bisimulations (a part of computer science). I am interested in a wide field of applications, in particular in some areas of finance, such as risk theory.

comment How to test that a distribution has infinite mean?
+1 but I would suggest moving that to one of mathematical websites: MSE or MO. Perhaps, cross-validated also could be useful

comment Risk theory is a part of financial mathematics
That I understand - I meant only the mathematical part. Anyways, say the problem of ruin probabilities will not classically fall into financial mathematics?

comment Risk theory is a part of financial mathematics
Even in the wikipedia article, they seem to consider both pricing and risk management as subsets of financial mathematics. The discussion on P and Q is indeed interesting, thanks for pointing it out.

NP, I just updated my description recently so it might have not been there before

comment George Soros models
Well, I am familiar with principles of the stochastic optimal control and dynamic programming. Surely, you can incorporate the reflexivity there - my question was rather on how to incorporate it in a practically meaningful way, that's why I've whether there are some financial models known that involve reflexivity as per Soros.

comment Why does Black-Scholes equation hold on continuation region of American Option?
For the American option, the solution is given by a Optimal Stopping/Free-boundary Problem. Here you seem to have European vanilla one

Just to clarify: do you mean market models, and so assumptions about the markets?

comment George Soros models
+1 Stochastic control is one area where some reflexivity is indeed present by definition. - can you be more specific here?

Thanks, I'll do that! (Btw, did you leave MSE?)

comment Dynamic hedging strategy example
Did you try using general method where the portfolio has to be a martingale like the one I suggested here?
