The Appled and Computational Mathematics seminar
combines lectures by our faculty, students and visitors
from other departments of George Mason University and
other institutions. This series serves the purpose of
fostering research collaborations and keeping us informed
of the recent advances in the field. Questions and
suggestions on possible contributions should be addressed
to Dan Anderson,
Harbir Antil, or
Igor Griva.
Everyone is Welcome to Attend!
Talks occur weekly on Fridays, 1:30pm  2:30pm in Exploratory Hall,
Room 4106, unless noted otherwise.
