Week's Talk

## Weekly Seminars

## Algebra, Combinatorics, Geometry, Topology (ACGT) Seminar

Tuesdays, 12:40 - 1:40 pm, AMB 164

This week: Speaker: Michael Falk (NAU), Title: A Catalan sighting: representations of sl_{2}.Abstract: In this “one-off” talk, I’ll sketch some of the (quite simple and beautiful) theory of representations of sl2(C), in order to exhibit yet another appearance of the Catalan numbers. Time permitting I’ll describe a curious Diophantine problem with interesting symmetry, that arose in our recent work (with A. Varchenko) about resonant weights in sl

_{2}discriminantal arrangements. Dane Jacobson will continue his talk about Spinpossible next Tuesday.## Applied Math Seminar

Thursdays, 12:45 - 1:35 pm, AMB 164

This week: Speaker Todd Wolford, Title: A Cantor Set of Nonconvergence, continued.

Abstract: I will present a brief paper published by my PhD advisor and another former faculty member at New Mexico Tech. The paper addresses the question: If the function is such that there are numbers a<b<c<d such that the intervals [a,b] and [c,d] are both mapped continuously onto [a,d] while the interval (b,c) is mapped (either immediately or asymptotically) to fixed points then what can we say about the iterative sequences of points that start in [a,d] and do not converge to a fixed point? (Possible orbits?, Measure?, Density?)
