Abstract: Let Mn(F)Mn(F) be the space of n×nn×n matrices over a field FF. A matrix A=(A(i,j))i,j=1n∈Mn(F) is weakly symmetric if A(i,j)≠0A(i,j)≠0 iff A(j,i)≠0A(j,i)≠0 holds for all i, j . A matrix is alternating if it is… read more here.

Abstract: We consider twisted equivariant K-theory for actions of a compact Lie group G on a space X where all the isotropy subgroups are connected and of maximal rank. We show that the associated rational spectral… read more here.
