Lattice homology and Seiberg-Witten Floer spectra

Irving Dai, Hirofumi Sasahira, Matthew Stoffregen

Using lattice homology, we give an explicit combinatorial description of the Seiberg-Witten-Floer spectrum $SWF (Y)$ for $Y$ an almost-rational plumbed homology sphere. Thi…

PL-genus of surfaces in homology balls

Jennifer Hom, Matthew Stoffregen, Hugo Zhou

We consider manifold-knot pairs $(Y, K)$ where $Y$ is a homology sphere that bounds a homology ball. We show that the minimum genus of a PL surface $Σ$ in a homology ball $X$ such t…
