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 sl2.
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 sl2 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?)
