Abstract: For a graded Liouville domain X, its symplectic cohomology (normally defined over the integers) can be lifted to a module over the complex cobordism ring using Floer homotopy theory. I'll discuss some computational aspects in the rational case, using Chern classes on Floer moduli spaces as well as X.Based on joint work-in-progress with Kenny Blakey.
