We establish a homological mirror theorem for the 4-manifolds arising as moduli of (irregular) rank two local systems on the projective line. Specifically, we prove that the Fukaya…

Trisections and Ozsvath-Szabo cobordism invariants
William E. Olsen
Given a smooth, compact four-manifold viewed as a cobordism from the empty set to its connected boundary, we demonstrate how to use the data of a trisection map $π:X^{4} \to \m…
