We introduce the\verb| Macaulay2| package\verb| RepHomology| for the computations of representation homology of certain spaces. The main methods implement computing the …

We define and study (derived) character maps of finite-dimensional representations of∞– groups. As models for∞–groups we take homotopy simplicial groups, ie the homotopy …
Let g be a finite-dimensional reductive Lie algebra (over R or C), h⊆ g its Cartan subalgebra, R⊂ h∗ a root system of g, Q= Q (R), the root lattice (spanned by R). Write the …
