PRIMEVAL ROTATION AND COSMICAL RINGS. II

Zeropoint Energies, Cosmical Constant, and Supersymmetry

Cox Rings and Combinatorics Ii

We study varieties with a finitely generated Cox ring. In the first part, we generalize a combinatorial approach developed in earlier work for varieties with a torsion free divisor class group to the case of torsion. Then we turn to modifications, e. g., blow-ups, and the question how the Cox ring changes under such maps. We answer this question for a certain class of modifications induced from...

On Smarandache Rings II

In this paper we show that a commutative semisimple ring is always a Smarandache ring. We will also give a necessary and sufficient condition for group algebra to be a Smarandache ring. Examples are provided for justification.

Generalized GCD Rings II

Greatest common divisors and least common multiples of quotients of elements of integral domains have been investigated by Lüneburg and further by Jäger. In this paper we extend these results to invertible fractional ideals. We also lift our earlier study of the greatest common divisor and least common multiple of finitely generated faithful multiplication ideals to finitely generated projectiv...
