  1. Tensor Categories, Z+-rings, and Grothendieck Rings

    Lee, Woo HyungWake Forest University2018

    In this paper, we will define and prove various properties of abelian categories, monoidal categories and tensor categories. Then, we will show how to define a ring that represents a tensor category, which will be called the Grothendieck Ring, and prove that it constitutes a very specific type of …

  5. Primitive near-rings

    Holcombe, William Michael LloydUniversity of Leeds1970

    The theory of near-rings has arisen in a variety of ways. There is a natural desire to generalise the theory of rings and skew fields by relaxing some of their defining axioms. It has also been the hope of some mathematicians that certain problems in group theory, particularly involving permutation …

There are sufficient examples to help the reader get a feel for real closed * rings and the real closure * of …

  7. On Semigroup Rings

    Runyan, Lawrence Paul

    Some of the properties of semigroup rings are described, illustrated and proved in this study. In particular, the central problem focuses on how various properties of the semigroup and ring are reflected in the resulting semigroup ring.

    Brennan, Joseph PatrickUniversity of Illinois at Urbana-Champaign2014

    A method is provided for the practical computation of the coefficients for a number of structural polynomials of the universal (lamda)-ring in one indeterminant. In particular, we derive a method for the computation of the inner product extending that of Lascoux. We also introduce a method that …

  15. Idempotents in group rings

    Marciniak, ZbigniewVirginia Polytechnic Institute and State University1982

    The von Neumann finiteness problem for k[G] is still open. Kaplansky proved it in characteristic zero. He used the nonvanishing of the trace: tr(e) = 0 implies e = 0 for any idempotent e ∊ k[G]. Assume now that char k = p > 0. Now tr can vanish on nonzero idempotents. Instead, we study the lifted …

In this context, a weak purity holds: if B is …
