David Chodounsky got his PhD in 2011 at the Charles University in Prague under the supervision of P. Simon and B. Balcar.
Starting October 2011 he works as a postdoctoral researcher at the Institute of Mathematics of the Czech Academy of Sciences and in July 2012 – June 2013 he is a postdoctoral fellow in Toronto.
His research is focused mainly on substructures of the powerset of integers.

David Chodounsky: A generalization of the Solovay–Tennenbaum theorem
Dear all,
The seminar meets on Wednesday November 29th at 11:00 in the Institute of Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.
Program:
David Chodounsky will present a generalization of the Solovay–Tennenbaum theorem; Assuming a diamond principle and given a suitable class PHI of ccc posets, there is a poset in the class PHI which forces MA(PHI) and c=kappa. continue reading…
