Shehzad Ahmed: Jónsson successors of singular cardinals

Wednesday, March 2 from 3 to 4pm Room: MB 124 Speaker: Shehzad Ahmed (Ohio University) Title: Jónsson successors of singular cardinals Abstract: We say that a cardinal $\lambda$ is a Jónsson cardinal if it satisfies the following weak Ramsey-type property: given any coloring $F:[\lambda]^{<\omega}\to \lambda$ of the finite subsets of $\lambda$ in $\lambda$-many colors, there exists a set $H\in[\lambda]^\lambda$ such that the range of $F\upharpoonright [H]^{<\omega}$ is a proper subset of $\lambda$. continue reading…
