Entropy of Compact Group Automorphisms

Based on MATH932 at the Ohio State University, Winter 1994. They cover a very short introduction to measure-theoretic and topological entropy, and are aimed at understanding part of Yuzvinskii's formula for the entropy of compact group automorphisms. Files are in pdf format.

Valuations and Dynamics

(prepared for PRODYN summer school, Gottingen 2001)

These notes are a summary of several problems in dynamics, and particularly the ergodic theory of Z^d-actions, where the theory of valuations play a role. The lecture notes are available as a single pdf file (560k). Revised 13 July 2001.

Topology

These are a set of lecture notes for a 3rd year undergraduate course in algebraic (simplicial) topology and the fundamental group. The lecture notes are available as a single pdf file (550k).

Functional Analysis

These are a set of lecture notes for a 3rd year undergraduate course in functional analysis. The lecture notes are available as a single pdf file (520k).
