An adjunction inequality for the Bauer-Furuta type invariants, with applications to sliceness and 4-manifold topology

Nobuo Iida, Anubhav Mukherjee, Masaki Taniguchi

Our main result gives an adjunction inequality for embedded surfaces in certain $4$-manifolds with contact boundary under a non-vanishing assumption on the Bauer--Furuta type invar…
