A rudimentary theory of topological 4D gravity

Abstract

A theory of topological gravity is a homotopy-theoretic representation of the Segal-Tillmann topologification of a two-category with cobordisms as morphisms. This note describes some relatively accessible examples of such a thing, suggested by the wall-crossing formulas of Donaldson theory. 1 Gravity categories A cobordism category has manifolds as objects… (More)
