Recent and upcoming talks by Osvaldo Guzmán González
Osvaldo Guzman Gonzalez: On weakly universal functions
Thursday, April 12, 2018, from 4 to 5:30pm
East Hall, room 3088
Speaker: Osvaldo Guzman Gonzalez (York University)
Title: On weakly universal functions
Abstract:
A function U:[omega_1]^2 —> 2 is called universal if for every function F:[omega_1]^2 —> omega there is an injective function h:omega_1 —> omega_1 such that F(alpha,beta)=U(h(alpha),h(beta)) for each alpha,betain omega_1. continue reading…
Osvaldo Guzman Gonzalez: On (1,w_1)weakly universal functions
Place: Fields Institute (Room 210)
Date: January 12, 2018 (13:3015:00)
Speaker: Osvaldo Guzman Gonzalez
Title: On (1,w_1)weakly universal functions
Abstract: We will study a very weak notion of universality of functions in Sacks models. continue reading…
Osvaldo Guzman Gonzalez: The ShelahSteprans property of ideals
Place: Fields Institute (Room 210)
Date: November 17, 2017 (13:3015:00)
Speaker: Osvaldo Guzman Gonzalez
Title: The ShelahSteprans property of ideals
Abstract: An ideal I has the ShelahSteprans property if for every set X of finite sets, there is an element of I that either intersects every element of X or contains infinitely many elements of X. continue reading…
Osvaldo Guzman Gonzalez: There are no Ppoints in Silver extensions
Place: Fields Institute (Room 210)
Date: September 29 , 2017 (13:3015:00)
Speaker: Osvaldo Guzman Gonzalez
Title: There are no Ppoints in Silver extensions
Abstract: We prove that after adding a Silver real no ultrafilter from the ground
model can be extended to a Ppoint, and this remains to be the case in any
further extension which has the Sacks property. continue reading…
