Combinatorics of Periods in Strings
We consider the set Gn of all period sets of strings of length n over a finite alphabet. We show that there is redundancy in period sets and introduce the notion of an irreducibl...

Query Answering and Containment for Regular Path Queries under Distortions
Abstract. We give a general framework for approximate query processing in semistructured databases. We focus on regular path queries, which are the integral part of most of the que...

The 2-SAT Problem of Regular Signed CNF Formulas
Signed conjunctive normal form (signed CNF) is a classical conjunctive clause form using a generalized notion of literal, called signed atom. A signed atom is an expression of the...
