SUMMARY:Number Theory Seminar: Alina Ostafe (UNSW)
DESCRIPTION:Title: Counting linear recurrence sequences with zeros and solv
 able S-unit equations\\r\\nAbstract: In this talk I will discuss recent jo
 int work with Carl Pomerance and Igor Shparlinski where we obtain a tight 
 upper bound on the number of integer linear recurrence sequences which att
 ain a zero value. The argument is based on modular techniques combined wit
 h a classical idea of P. Erdos. Using similar ideas\, we also show that on
 ly a rather small proportion of linear equations are solvable in elements 
 of a fixed finitely generated subgroup of a multiplicative group of a numb
 er field.\\r\\nAlte Universität - Seminarraum -201
