Surface configuration kernels

Andreas Stavrou

Let $Σ_{g, *}$ be a once-punctured oriented surface of genus $g$ . We study the action of the mapping class group $Γ_{g, *}$ on the $n^{t h}$ rational cohomology of the configuration s…

Superposition of configurations and scanning

Andreas Stavrou

We endow the cohomology of configuration spaces of a manifold with a product arising from superposing configurations. We prove that, under the scanning isomorphism, this product co…

Non-trivial action of the Johnson filtration on the homology of configuration spaces

Andrea Bianchi, Andreas Stavrou

We let the mapping class group $Γ_{g, 1}$ of a genus $g$ surface $Σ_{g, 1}$ with one boundary component act on the homology $H_{*} (F_{n} (Σ_{g, 1}); Q)$ of the $n^{t h}$ ordered c…
