Equivariant Nielsen fixed point theory for n-valued maps

We develop an equivariant Nielsen fixed point theory for n-valued G-maps by associating (as in Better (2010) [2]) an abstract simplicial complex to any equivariant n-valued map and defining, in terms of this complex, two n-valued continuous G-homotopy invariants that are lower bounds for the number of fixed points and of orbits in the n-valued continuous G-homotopy class of a given n-valued G-map. We also provide an equivariant Hopf construction for n-valued G-maps as well as a minimality result for the Nielsen numbers introduced in this setting.
