## Abstract

I will start by describing the ideas involved in constructing Quantum cohomology and intersection Floer homology. I will then talk about the differences between these two and how the latter leads to the notion of curved \(A_\infty\) algebras (the former does not). I will then discuss an explicit model for handling curved \(A_\infty\) algebras and how we hope to lift this to spectra - with the ultimate goal of lifting intersection Floer homology itself to a construction in spectra. This is joint work with M. Abouzaid and A. Blumberg.
