On binomial set-theoretic complete intersections in characteristic p.
On Bruck-Reilly extensions.
On cardinalities of row spaces of Boolean matrices.
On Cayley graphs of completely 0-simple semigroups
We give necessary and sufficient conditions for various vertex-transitivity of Cayley graphs of the class of completely 0-simple semigroups and its several subclasses. Moreover, the question when the Cayley graphs of completely 0-simple semigroups are undirected is considered.
