Pointed Admissible G-covers and G-equivariant Cohomological Field Theories
For any finite group G we define the moduli space of pointed admissible G-covers and the concept of a G-equivariant cohomological field theory (G-CohFT), which, when G is the trivial group, reduce to the moduli space of stable curves and a cohomological field theory (CohFT), respectively. We prove that taking the “quotient” by G reduces a G-CohFT to a CohFT. We also prove that a G-CohFT contain...

متن کاملExercises in Equivariant Cohomology and Topological Theories
Before going into the subject of this talk, I would like to describe some concrete exercises done by Claude and I which represent a very small portion of the numerous discussions we had, mostly by exchange of letters. We happened to be both guests of the CERN theory division during the academic year 19721973. The perturbative renormalization of gauge theories was still a hot subject, and, where...
متن کاملSupersymmetric Gauge Theories, Vortices and Equivariant Cohomology
We construct actions for (p, 0)-and (p, 1)-supersymmetric, 1 ≤ p ≤ 4, two-dimensional gauge theories coupled to non-linear sigma model matter with a Wess-Zumino term. We derive the scalar potential for a large class of these models. We then show that the Euclidean actions of the (2, 0) and (4, 0)-supersymmetric models without Wess-Zumino terms are bounded by topological charges which involve th...
متن کاملMorphisms of Cohomological Field Theories
We introduce a notion of morphism of CohFT’s, on the basis of the analogy with A∞ morphisms, and discuss the relationship with morphisms of F -manifolds introduced by Manin and Hertling [5]. The structure maps of a morphism of CohFT’s have as input a cohomology class on the moduli space of scaled affine lines (complexified multiplihedron) studied in Ma’u-Woodward [9]. The main result is a compu...
