Stable Spin Maps, Gromov-Witten Invariants, and Quantum Cohomology
Tyler J. Jarvis, Takashi Kimura, Arkady Vaintrob
We introduce the stack of r-spin maps. These are stable maps into a variety V from n-pointed algebraic curves of genus g, with the additional data of an r-spin structure on the cur…

Gravitational Descendants and the Moduli Space of Higher Spin Curves
Tyler J. Jarvis, Takashi Kimura, Arkady Vaintrob
The purpose of this note is introduce a new axiom (called the Descent Axiom) in the theory of -spin cohomological field theories. This axiom explains the origin of gravitational…
