报告摘要  Abstract

Many graph polynomials have only real zeros, such as matching polynomials and characteristic polynomials of graphs, as well as independence polynomials of claw-free graphs. Graph polynomials enjoy various recurrence relations. In this talk we establish some sufficient conditions to the reality of zeros of polynomial sequences satisfying certain recursions and then apply them to solve some related problems in a unified approach.
