#### A 50-minute peek into the quasi-world

###### Matthew Romney (UIUC Math)

Abstract: Quasiconformal geometry is the dominant research area which evolved from complex analysis in the 20th century and remains active today. This talk will give a friendly overview to the subject, from its roots in the classical Riemann mapping theorem and Liouville theorem on conformal mappings, to some of its compelling applications in other fields, including complex dynamics and geometric group theory.

#### Curvature of graphs

###### Moon Duchin (Tufts University)

Abstract: I'll discuss some ideas for measuring curvature of graphs that carry over to the setting of large finite graphs, including discrete Ricci curvature and cotangent-weighting. There's an interesting interplay of ideas from pure math (geometric group theory) and theoretical computer science (mesh clustering and smoothing), with potential practical applications to the study of electoral redistricting.
