# Gromov-Witten Theory of Spin Curves and Orbifolds

Share this page *Edited by *
*Tyler J. Jarvis; Takashi Kimura; Arkady Vaintrob*

This volume is a collection of articles on orbifolds,
algebraic curves with higher spin structures, and related invariants of
Gromov-Witten type. Orbifold Gromov-Witten theory generalizes quantum
cohomology for orbifolds, whereas spin cohomological field theory is based on
the moduli spaces of higher spin curves and is related by Witten's conjecture
to the Gelfand-Dickey integrable hierarchies.

A common feature of these two very different looking theories is the central
role played by orbicurves in both of them. Insights in one theory can often
yield insights into the other. This book brings together for the first time
papers related to both sides of this interaction. The articles in the
collection cover diverse topics, such as geometry and topology of orbifolds,
cohomological field theories, orbifold Gromov-Witten theory, \(G\)-Frobenius algebra and singularities, Frobenius manifolds and Givental's quantization
formalism, moduli of higher spin curves and spin cohomological field
theory.

#### Readership

Graduate students and research mathematicians interested in algebraic geometry, topology, and mathematical physics.
