**CANCELED** Lifting cobordisms and Kontsevich-type recursions for counts of real curves **CANCELED**
March 17, 2020 11:00 amSpeaker: Xujia Chen
Kontsevich's recursion, proved in the early 90s, is a recursion formula for the counts of rational holomorphic curves in complex manifolds. For complex fourfolds and sixfolds with a real structure...

**CANCELED** Knots with all prime power branched covers bounding rational homology balls
March 13, 2020 3:30 pmSpeaker: Allison Miller
Given a slice knot K and a prime power n, the n-th cyclic branched cover \Sigma_n(K) bounds a rational homology ball (Casson-Gordon). Even if one restricts to n=2, this gives a powerful sliceness...

CMSA Colloquium: Menu Costs and the Volatility of Inflation
March 11, 2020 4:30 pmSpeaker: Jose Scheinkman
We present a state-dependent equilibrium pricing model that generates inflation rate fluctuations from idiosyncratic shocks to the cost of price changes of individual firms. A firm's nominal price increase lowers...
