Abstract
The reduction of the fundamental lemma for arbitrary spherical Hecke operators to the case of the unit elements of the spherical Hecke algebra for the case of twisted endoscopy, although formulated only for G′ = GSp(4) and base change in this chapter, holds for twisted endoscopy in greater generality. However, to avoid technical considerations, we restrict ourselves here to the special case. The general case will be considered elsewhere [113].
