Tensor Categories, Z+-rings, and Grothendieck Rings
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 …

Torsion Units of Integral Group Rings and Scheme Rings
… Z with nice bases. These include integral group rings, integral adjacency algebras of association schemes and integral C-algebras. Torsion units of group rings have been studied extensively since the 1960’s. Much of the attention has been devoted to the Zassenhaus conjecture for normalized …

Primitive near-rings
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 …

Real Closed * Rings
… of real closure of commutative unitary reduced rings. I also give a characterization of rings that are real closed in this context and how one is able to arrive to such a real closure. There are sufficient examples to help the reader get a feel for real closed * rings and the real closure * of …

On Semigroup Rings
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.

Products in Lambda-Rings
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 …

Dehydration of apple rings
… and ring thickness, on the drying rates of apple rings, is reported. Drying rates for different apple slice thicknesses are correlated with the total moisture content of the fruit and the air relative humidity. Also reported are results on the simulation, both experimental and computational, for …

Idempotents in group rings
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 …

Troupers: Essays in Three Rings
Troupers: Essays in Three Rings is a collection of fourteen essays focused mainly on variety entertainers (including the author). It leads the reader through a menagerie of the author's own enthusiasms--from clowning and circus elephants, to hot jazz and the ukulele. While the primary occupation of …

Weak Purity for Gorenstein Rings
… $B\to A$ is a module finite extension of normal rings, unramified in codimension one with B an excellent local equicharacteristic Gorenstein domain of dimension at least five (under additional conditions, the mixed characteristic case is considered). In this context, a weak purity holds: if B is …
