Applied and Computational Math Seminar

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.
