Abstract
Equivariant Loday constructions are a means for providing geometric interpretations of equivariant homology theories. They are usually constructed for a simplicial -set and a -Tambara functor. We study situations where -- depending on the isotropy subgroups occurring in the simplicial -set -- one can work with -Tambara functors for a suitable subgroup of . We apply this to give an interpretation of Real Hochschild homology of discrete -rings as equivariant Loday constructions where we consider -gons with a geometrically defined action of the dihedral groups for all . The action of symmetric groups on -skeleta of permutohedra also gives examples with isotropy groups .
