Floer homotopy theory, revisited

Ralph L. Cohen

In 1995 the author, Jones, and Segal introduced the notion of "Floer homotopy theory". The proposal was to attach a (stable) homotopy type to the geometric data given in a version…

Twisted Calabi-Yau ring spectra, string topology, and gauge symmetry

Ralph L. Cohen, Inbar Klang

In this paper, we import the theory of "Calabi-Yau" algebras and categories from symplectic topology and topological field theories to the setting of spectra in stable homotopy the…

Homotopy automorphisms of R-module bundles, and the K-theory of string topology

Ralph L. Cohen, John D. S Jones

Let be a ring spectrum and an -module bundle of rank . Our main result is to identify the homotopy type of the group-like monoid of homotopy automorphisms of th…

Gauge theory and string topology

Ralph L. Cohen, John D. S. Jones

Given a principal bundle over a closed manifold, G --> P --> M, let P^{Ad} --> M be the associated adjoint bundle. Gruher and Salvatore showed that the Thom spectrum (P^{Ad})^{-TM}…

Stability for closed surfaces in a background space

Ralph L. Cohen, Ib Madsen

In this paper we present a new proof of the homological stability of the moduli space of closed surfaces in a simply connected background space , which we denote by . T…

Stability phenomena in the topology of moduli spaces

Ralph L. Cohen

The recent proof by Madsen and Weiss of Mumford's conjecture on the stable cohomology of moduli spaces of Riemann surfaces, was a dramatic example of an important stability theorem…
