of Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.
Program: Viera Šottová — The critical cardinality of spaces with
respect to the ideal version of S_1(P,R)
I will present the second part a joint paper with J. Šupina which
focuses on critical cardinality of the ideal version of sequence
selection principles. If I, J are arbitrary ideals on omega, then the
critical cardinality of S_1(I-Gamma, J-Gamma) can be described by the
cardinal lambda(I,J) in the case of covers. Therefore we investigate
lambda(I,J) and its relation to the other cardinals. This will be the
main point of this talk.
