Piotr Koszmider is a professor of mathematics at the Mathematical Institute of the Polish Academy of Sciences in Warsaw. He received his Ph.D. at the University of Toronto in 1992 and since then has done mathematics in Canada, Israel, the US, Brazil and recently in Poland.

His mathematical interests have evolved starting with forcing theory, Boolean algebras and stepping-up principles, through topology to the present applications of forcing, combinatorial set theory and analytic topology in Banach spaces and algebras of operators acting on them.

Alan Dow Conference, December 6–9, 2014

60 years of Dow
celebrating the mathematics
of Alan Dow
December 6–9, 2014

Alan Dow has made deep contributions to set-theoretic topology and has been one of few researchers to pioneer new techniques in set theory which were directly motivated by fundamental topological problems. continue reading…
