Holomorphic curves in Stein domains and the tau-invariant
Antonio Alfieri, Alberto Cavallo
The scope of the paper is threefold. First, we build on recent work by Hayden to compute Hedden's tau-invariant in the case when is a Stein fillable contact structure…

Involutions and the Chern-Simons filtration in instanton Floer homology
Antonio Alfieri, Irving Dai, Abhishek Mallick +1
Building on the work of Nozaki, Sato and Taniguchi, we develop an instanton-theoretic invariant aimed at studying strong corks and equivariant bounding. Our construction utilizes t…
