Oct. 13, 2011

Network connectivity during mergers and growth: Optimizing the addition of a module Dane Taylor Applied Mathematics , University of Colorado Boulder Date and time: Thursday, October 13, 2011 - 4:00pm Abstract: The principal eigenvalue λ of a network’s adjacency matrix often determines dynamics on the network (e.g., in synchronization and...

Computational Math Seminar: Jehanzeb Hameed Chaudhry

Oct. 11, 2011

A Goal-Oriented Approach to Least-Squares Finite Element Methods Jehanzeb Hameed Chaudhry Department of Mathematics, Colorado State University Date and time: Tuesday, October 11, 2011 - 3:45pm Abstract: In this talk we introduce an approach that augments least-squares finite element formulations with user-specified goals or quantities-of-interest. The method incorporates the quantity-of-interest...
