Abstract: Let S be a compact Riemann surface and let H be a finite group. It is known that if H acts on S , then there is a H -equivariant isogeny decomposition of the Jacobian… read more here.

DOI: 10.1007/s11083-016-9417-9
Abstract: The symmetric group Sn$\mathfrak {S}_{n}$ acts naturally on the poset of injective words over the alphabet {1, 2,…,n}. The induced representation on the homology of this poset has been computed by Reiner and Webb. We… read more here.

DOI: 10.1016/j.aim.2021.107793
Abstract: We state a conjecture about the Weyl group action coming from Geometric Satake on zero-weight spaces in terms of equivariant multiplicities of Mirkovic-Vilonen cycles. We prove it for small coweights in type A. In this… read more here.

DOI: 10.3390/axioms11100505
Abstract: In this paper, we characterize spaces of L∞-functions on a compact Hausdorff space that are invariant under a transitive and continuous group action. This work is analogous to established results concerning invariant spaces of continuous… read more here.
