JIM HAGLUND
I am a Professor of Mathematics here at Penn.
I am co-organizer
(with
Elizabeth Beazley of Haverford College,
Linda Chen of Swarthmore College,
Jennifer Morse of Drexel University, and
Mark Skandera of Lehigh University) of the
Philadelphia CAGE (Combinatorics and Algebraic Geometry)
seminar (Certain Tuesdays and Thursdays afternoons from 2 to 3pm in DRL 4C2).
Last years CAGE seminar
My research interests are in algebraic and enumerative
combinatorics.
In particular, I work on problems involving symmetric functions and Macdonald polynomials,
combinatorial statistics and q-analogs,
rook polynomials, and am also interested in the zeros of polynomials and analytic functions.
I like experimental mathematics, and
often use computer algebra packages such as Maple in my research, to develop
and test conjectures.
