A Biased Motivation: Idempotents in Group Algebras,d as the space of functions .: Γ → C with finite support. The product in CΓ is induced by the multiplication in Γ. Namely, for .and . elements in CΓ, then . which is the usual convolution of . and ., and thus . for all . ∈Γ.

The Dirac-dual Dirac Method,. ∈ ..(.)and . ∈ .. (that is, we view . as a bi-module over itself and require ..(.) to act on . by endomorphisms of bi-modules); if a net {..} in ..(.)converges to 1 uniformly on compact subsets of ., then . for all . ∈ .. Note that if . is unital, . defines a homomorphism ..
