Winterschool

Jan 28—Feb 4, 2017

The Winter School in Abstract Analysis (section Set Theory) is a traditional conference for mathematicians working in diverse areas of Set Theory, Topology and Analysis. The school is a meeting where emphasis is put on the joy of doing mathematics. The invited speakers for this year are

D. Asperó, J. Bagaria, Ch. Brech, A. Marks.

Research Interests

My main area of interest is Set Theory, in particular combinatorics of $\omega$. Anything having to do with (ultra)filters will certainly pique my interest. Some of my recent work centers around definable ideals on $\omega$ and (generalized) Mathias forcing. I also occasionaly dabble with general and set-theoretic topology. I didn't (yet?) do any research in computer science, but it definitely is an interesting area.
