  • Finitary incidence algebras. 

    Wagner, Bradley M. (, 2014-06-11)
    Let P be an arbitrary partially ordered set and I(P) its incidence space. Then F(P) is the finitary incidence algebra and I(P) is a bimodule over it. Consequently we can form D(P) = FI(P) ⊕ I(P) the idealization of I(P). ...
  • On rings with distinguished ideals and their modules. 

    Buckner, Joshua. (2007-05-23)
    Let S be an integral domain, R an S algebra, and F a family of left ideals of R. Define End(R, F) = {φ ∈ End(R+) : φ(X ) ⊆ X for all X ∈ F }. In 1967, H. Zassenhaus proved that if R is a ring such that R+ is free of finite ...
