Schur Q-functions and a Kontsevich-Witten genus
نویسندگان
چکیده
The Virasoro operations in Witten’s theory of two-dimensional topological gravity have a homotopy-theoretic interpretation as endomorphisms of an ordinary cohomology theory with coefficients in a localization of I. Schur’s ring ∆ of Q-functions. The resulting theory has many of the features of a vertex operator algebra.

Partition Functions of Matrix Models as the First Special Functions of String Theory II. Kontsevich Model
In arXiv:hep-th/0310113 we started a program of creating a reference-book on matrix-model τ -functions, the new generation of special functions, which are going to play an important role in string theory calculations. The main focus of that paper was on the one-matrix Hermitian model τ functions. The present paper is devoted to a direct counterpart for the Kontsevich and Generalized Kontsevich ...
متن کاملThe Tautological Rings of the Moduli Spaces of Stable Maps to Flag Varieties
We show that the rational cohomology classes on the moduli spaces of genus zero stable maps to SL flag varieties are tautological. The Kontsevich moduli stacks of stable maps arise as generalizations of the classical Deligne-Mumford spaces of stable curves. Their intersection theory has been intensively studied in the last decade in relation to enumerative geometry and string theory. Partial re...
متن کاملPositivity Questions for Cylindric Skew Schur Functions
Recent work of A. Postnikov shows that cylindric skew Schur functions, which are a generalisation of skew Schur functions, have a strong connection with a problem of considerable current interest: that of finding a combinatorial proof of the non-negativity of the 3-point Gromov-Witten invariants. After explaining this motivation, we study cylindric skew Schur functions from the point of view of...
متن کاملThe N-point Functions for Intersection Numbers on Moduli Spaces of Curves
Abstract. Using the celebrated Witten-Kontsevich theorem, we prove a recursive formula of the n-point functions for intersection numbers on moduli spaces of curves. It has been used to prove the Faber intersection number conjecture and motivated us to find some conjectural vanishing identities for Gromov-Witten invariants. The latter has been proved recently by X. Liu and R. Pandharipande. We a...
متن کاملMirzakharni’s Recursion Formula Is Equivalent to the Witten-kontsevich Theorem
In this paper, we give a proof of Mirzakhani's recursion formula of Weil-Petersson volumes of moduli spaces of curves using the Witten-Kontsevich theorem. We also describe properties of intersections numbers involving higher degree κ classes.
