Instantons, the Information Metric, and the AdS/CFT Correspondence
Matthias Blau, K. S. Narain, George Thompson
We describe some remarkable properties of the so-called Information Metric on instanton moduli space. This Metric is manifestly gauge and conformally invariant and coincides with t…
On the Relationship between the Rozansky-Witten and the 3-Dimensional Seiberg-Witten Invariants
Matthias Blau, George Thompson
The Seiberg-Witten analysis of the low-energy effective action of d=4 N=2 SYM theories reveals the relation between the Donaldson and Seiberg-Witten (SW) monopole invariants. Here…
On the Generalized Casson Invariant
George Thompson
The path integral generalization of the Casson invariant as developed by Rozansky and Witten is investigated. The path integral for various three manifolds is explicitly evaluated.…
Lectures on 2d Gauge Theories: Topological Aspects and Path Integral Techniques
Matthias Blau, George Thompson
These are lecture notes of lectures presented at the 1993 Trieste Summer School, dealing with two classes of two-dimensional field theories, (topological) Yang-Mills theory and the…
1992 Trieste Lectures on Topological Gauge Theory and Yang-Mills Theory
George Thompson
In these lecture notes we explain a connection between Yang-Mills theory on arbitrary Riemann surfaces and two types of topological field theory, the so called and cohomologic…
