WAKE FOREST UNIVERSITY DEPARTMENT OF MATHEMATICS & STATISTICS Presents Yan Zhang Davidson College Tuesday, October 15th, 2019 11am Carswell Hall, Room 101 Abstract: We present a general formula describing the joint distribution of two permutation statistics—the peak number and the descent number—over any set of permutations whose quasisymmetric generating function…
WAKE FOREST UNIVERSITY DEPARTMENT OF MATHEMATICS & STATISTICS Presents John Holmes Wake Forest University Thursday, September 26th, 2019 11am Carswell Hall, Room 101 Abstract: Nonlinear PDEs are difficult to solve explicitly. Therefore, mathematicians are interested in discovering properties about the solutions, by using and developing analytical techniques. The first questions…
WAKE FOREST UNIVERSITY DEPARTMENT OF MATHEMATICS & STATISTICS Presents Luigi Ferraro Wake Forest University Thursday, September 19th, 2019 11am Carswell Hall, Room 101 Abstract: Group actions are ubiquitous in mathematics. To study an algebraic object it is often useful to understand what groups act on it. A major role in…
WAKE FOREST UNIVERSITY DEPARTMENT OF MATHEMATICS & STATISTICS Presents Nancy Scherich Wake Forest University Thursday, September 12th, 2019 11am Carswell Hall, Room 101 Abstract: Many well known representations of the braid groups are parameterized by a complex parameter, such as the Burau, Jones, and BMW representations. I will give a…
WAKE FOREST UNIVERSITY DEPARTMENT OF MATHEMATICS & STATISTICS Presents Mike Weselcouch Wake Forest University Thursday, September 5th, 2019 11am Carswell Hall, Room 101 The (P,ω)-partition generating function of a labeled poset (P,ω) is a quasisymmetric function enumerating certain order-preserving maps from P to ℤ+. We study the expansion of this…
