The topological and smooth Hausmann-Weinberger invariants disagree

Mike Miller Eismeier

For $π$ a finitely presented group, Hausmann and Weinberger defined $q (π) \in Z$ to be the minimum Euler characteristic over all closed, oriented $4$ -manifolds with fundame…

Framed instanton homology and Frøyshov's invariant

Sudipta Ghosh, Mike Miller Eismeier

We determine the framed instanton homology with coefficients in $F = Z /2$ for Dehn surgeries on a knot in the $3$ -sphere. The dimension of these groups is seen to h…

A Lefschetz decomposition over $Z$ , and applications

Analisa Faulkner Valiente, Mike Miller Eismeier

We discuss a 'Lefschetz filtration' of $Λ^{*} (Z^{2 g})$ and prove its subquotients are isomorphic as $Sp (2 g)$ -modules to primitive subspaces $P^{k} (Z^{2 g})$ . This…
