Some applications of a theorem of Schur to graphs and to a class of endomorphisms
Some applications of graph theory in the theory of hypergraphs
Some applications of pq-groups in graph theory
We describe some new applications of nonabelian pq-groups to construction problems in Graph Theory. The constructions include the smallest known trivalent graph of girth 17, the smallest known regular graphs of girth five for several degrees, along with four edge colorings of complete graphs that improve lower bounds on classical Ramsey numbers.

Some classes of Diophantine equations connected with McFarland's and Ma's conjectures
In this paper we consider some special classes of Diophantine equations connected with McFarland's and Ma's conjectures about difference sets in abelian groups and we obtain an extension of known results.

Some Classes of Integral Graphs Which Belong to the Class Alpha Ka u Beta Kb,b
Some classes of numbers and derivatives.
Some classes of perfect strongly annihilating-ideal graphs associated with commutative rings
Let be a commutative ring with identity and be the set of ideals with nonzero annihilator. The strongly annihilating-ideal graph of is defined as the graph with the vertex set and two distinct vertices and are adjacent if and only if and . In this paper, the perfectness of for some classes of rings is investigated.
