Recent and upcoming talks by Jan Grebík
Jan Grebík: Borel chromatic numbers
Dear all,
The seminar meets on Wednesday July 18th at 11:00 in the Institute of
Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.
Program: Jan Grebík — Borel chromatic numbers
I will present an overview of known facts about Borel chromatic numbers
of Borel graphs. continue reading…
Jan Grebik: Applications of topological dynamics to graphons
The seminar meets on Wednesday February 28th at 11:00 in the Institute
of Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.
Program: Jan Grebik — Applications of topological dynamics to graphons
We show that the question about the existence of a Borel or continuous
lift for graphons has its counterpart in topological dynamics. continue reading…
Jan Grebik: Borel selector for Hypergraphons
The seminar meets on Wednesday January 3rd at 11:00 in the Institute of
Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.
Program: Jan Grebik — Borel selector for Hypergraphons
We recall all relevant definitions and show that there is a Borel way of
choosing a concrete representant of a hypergraphon. continue reading…
Jan Grebik: Borel selectors of Borel ideals (continued)
Dear all,
The seminar meets on Wednesday October 25th at 11:00 in the Institute of
Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.
Program: Jan Grebik — Borel selectors of Borel ideals (continued)
We present a result that there is an F_sigma ideal without Borel
selector and deduce that Galvin’s lemma does not have a “Borel proof.”
We also show that NashWilliams theorem has a “Borel proof” and
therefore Galvin’s lemma is intrinsically more complex than
NashWilliams theorem. continue reading…
