Singularities with Symmetries, orbifold Frobenius algebras and Mirror Symmetry

Ralph M. Kaufmann

Previously, we introduced a duality transformation for Euler $G$ --Frobenius algebras. Using this transformation, we prove that the simple $A, D, E$ singularities and Pham singulariti…

Pointed Admissible G-Covers and G-equivariant Cohomological Field Theories

Tyler J. Jarvis, Ralph Kaufmann, Takashi Kimura

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 trivi…
