Query: C*-algebras of endomorphisms of groups with finite cokernel and partial
  actions   In this paper we extend the constructions of Boava and Exel to present the
C*-algebra associated with an injective endomorphism of a group with finite
cokernel as a partial group algebra and consequently as a partial crossed
product. With this representation we present another way to study such
C*-algebras, only using tools from partial crossed products.
