Abstract: Abstract We study the graph of zero-divisors of a quadratic quotient of a Rees algebra. We provide conditions in order to determine its girth and diameter, extending several results regarding amalgamated duplications and Nagata’s idealization. read more here.

Abstract: Let Pn be the partial transformation semigroup on Xn = {1, 2, . . . , n} . In this paper, we find the left zerodivisors, right zero-divisors and two sided zero-divisors of Pn ,… read more here.
