From Nondeterministic Suffix Automaton to Lazy Suffix Tree
Given two strings, a pattern P of length m and a text T of length n over some alphabet of size , we consider the exact string matching problem, i.e. we want to report all occurren...

Finding Roots of Unity Among Quotients of the Roots of an Integral Polynomial
We present an efficient algorithm for testing whether a given integral polynomial has two distinct roots a, B such that fflp is a root of unity. The test is based on results obtai...
