Some more Problems about Orderings of Ultrafilters [PDF]

open access: yes, 2010
We discuss the connection between various orders on the class of all the ultrafilters and certain compactness properties of abstract logics and of topological spaces. We present a model theoretical characterization of Comfort order.

On continuity of measurable group representations and homomorphisms [PDF]

open access: yes, 2015
Let G be a locally compact group, and let U be its unitary representation on a Hilbert space H. Endow the space L(H) of linear bounded operators on H with weak operator topology. We prove that if U is a measurable map from G to L(H) then it is continuous.

Dirichlet sets and Erdos-Kunen-Mauldin theorem [PDF]

open access: yes, 2007
By a theorem proved by Erdos, Kunen and Mauldin, for any nonempty perfect set $P$ on the real line there exists a perfect set $M$ of Lebesgue measure zero such that $P+M=\mathbb{R}$.
