In this paper we study a generalization of the classical notions of bordered and unbordered words, motivated by DNA computing. DNA strands can be viewed as finite strings over th...
Partial words are finite sequences over a finite alphabet A that may contain a number of “do not know” symbols denoted by ’s. Setting A = A ∪ { }, A∗ denotes the set o...
Given a connected bipartite graph G, we describe a procedure which enumerates and computes all graphs H (if any) for which there is a direct product factorization G ∼= H × K2. W...
