Welcome 










My name is Piotr Koszmider, since the second semester of 2010/11 I have been working
at the Mathematical Institute of the Polish of Academy of Sciences.
I was born in Łód where I graduated from
XXXI LO High School in 1983. After
graduating from
University of Warsaw in 1988.
I left Poland and since then I had been working abroad
(Canada, Israel, USA, Brasil). In 2007 I came back to Poland.
 














What I do 










 create concepts which help me to discover new mathematical truths,
 publish the results of these discoveries in international mathematical journals or as
chapters of books. Before that, they circulate as preprints
 do
research projects which are financed by governmental agencies
 supervise master's dissertations
 supervise Ph. D. Theses
 do projects with undergraduate students
 have classes with graduate students
 have classes with undergraduate students
 organize conferences
 participate in conferences
 visit other mathematical centers and present my work there and collaborate
 receive visits to collaborate with mathematicians of other centers
 














Research Interests 











Settheoretic methods in C*algebras, especially nonseparable approximatelly finitedimensional algebras,
scattered C*algebras, the Calkin algebra.

Settheoretic methods in Banach spaces and the algebras of operators acting on them, especially Banach spaces of continuous functions
In particular I am interested in
the structure of complemented subspaces, biorthogonal systems, and linear
operators. I use mainly infinitary methods, sometimes forcing.
 Applications of forcing.
 Combinatorial set theory, among others, combinatorial principles
which hold in L, and principles which follow from the existence of large cardinals
 Boolean algebras and compact spaces via the Stone duality in the contet of functional analysis.
In particular, cardinal functions on Boolean algebras. Dual balls with weak* topology.
Radon measures on compact spaces as linear functionals on the spaces of continuous
functions considered with weak* or weak topology.
 Independence and consistency proofs. Undecidability of
interesting analytic, algebraic or topological problems
