• #### Convergence and approximation for primal-dual methods in large-scale optimization ﻿

(1990)
Large-scale problems in convex optimization often can be reformulated in primal-dual (minimax) representations having special decomposition properties. Approximation of the resulting high-dimensional problems by restriction ...
• #### Convexity, convergence and feedback in optimal control ﻿

(2000)
The results of this thesis are oriented towards the study of convex problems of optimal control in the extended piecewise linear-quadratic format. Such format greatly extends the classical linear-quadratic regulator problem ...
• #### An electrodynamic inverse problem in chiral media ﻿

(1998)
We consider the inverse problem of determining the electromagnetic material parameters of a body from information obtainable only at the boundary of the body; such information comes in the form of a boundary map which we ...

• #### Strichartz estimates for wave equations with coefficients of Sobolev regularity ﻿

(2005)
Wave packet techniques provide an effective method for proving Strichartz estimates on solutions to wave equations whose coefficients are not smooth. In this work, such methods are used to show Strichartz inequalities for ...
• #### The topology of graph homomorphisms ﻿

(2007)
In this thesis we consider topological aspects of graph homomorphisms. Our main object of study is the Hom complex of graphs, a space first introduced by Lovasz to obtain lower bounds on chromatic number, and more recently ...
