Smoothing Techniques for Computing Nash Equilibria of Sequential Games
We develop first-order smoothing techniques for saddle-point problems that arise in the Nash equilibria computation of sequential games. The crux of our work is a construction of ...

Rational canonical form of polyphase matrices with applications to designing paraunitary filter banks
In this paper we consider the rational canonical form of arbitrary polyphase matrices and use it to derive a simple implementation of paraunitary filter banks (PUFBs) based on a c...
