DESCRIPTION:Speaker:  Maya Sankor (Stanford)\n\nTitle:  The Tur\'an Number 
 of Homeomorphs\n\nAbstract:\n\nLet $X$ be a 2-dimensional simplicial comple
 x. Denote by $\text{ex}_{\hom}(n\,X)$ the maximum number of 2-simplices in 
 an $n$-vertex simplicial complex that has no sub-simplicial complex homeomo
 rphic to $X$. The asymptotics of $\text{ex}_{\hom}(n\,X)$ have recently bee
 n determined for all surfaces $X$. I will discuss these results\, as well a
 s some techniques for bounding $\text{ex}_{\hom}(n\,X)$ for arbitrary 2-dim
 ensional simplicial complexes $X$.
