Finite Groups with a Prescribed Number of Cyclic Subgroups II
Richard Belshoff, Joe Dillstrom, Les Reid
Tărnăuceanu described the finite groups having exactly cyclic subgroups. In "Finite Groups with a Prescribed Number of Cyclic Subgroups,", we used elementary methods to…

Properties of Generalized Derangement Graphs
Hannah Jackson, Kathryn Nyman, Les Reid
A permutation sigma in Sn is a k-derangement if for any subset X = {a1, . . ., ak} \subseteq [n], {sigma(a1), . . ., sigma(ak)} is not equal to X. One can form the k-derangement gr…
Some Results On Normal Homogeneous Ideals
Les Reid, Leslie G. Roberts, Marie A. Vitulli
In this article we investigate when a homogeneous ideal in a graded ring is normal, that is, when all positive powers of the ideal are integrally closed. We are particularly intere…
