Thilo Weinert: Avoiding Quadruples Using a Scale

BIU seminar in Set Theory On 08/06/2017, 10-12, Building 604, Room 103 Speaker: Thilo Weinert (BGU) Title: Avoiding Quadruples Using a Scale Abstract. In 1971, Hajnal showed that the continuum hypothesis implies omega_1^2 -|-> (omega_1^2, 3)^2 and in the same year, together with Erdős, that GCH implies that for every infinite cardinal kappa and every alpha < (kappa^+)^2 we have alpha -|-> (kappa^+ * kappa, 3)^2. continue reading…

Thilo Weinert: Partition relations for linear orders in a non-choice context

Monday, November 18, 2013, 16.30 Seminar room 0.011, Mathematisches Institut, Universität Bonn Speaker: Thilo Weinert (Universität Bonn) Title: Partition relations for linear orders in a non-choice context Abstract: In “Partition Relations for eta_alpha-Sets”, Erdös, Milner and Rado proved, using the Axiom of Choice, three partition relations which amount to the following: -It is possible to partition the triples of any linear order into two classes such that every set of order-type w* + w(the integers) contains a triple in the first class and every quadruple contains a triple in the second class. continue reading…
