Yano's conjecture for 2-Puiseux pair irreducible plane curve singularities

Algebraic Geometry 2018-05-04 v2

Abstract

In 1982, Yano proposed a conjecture predicting the bb-exponents of an irreducible plane curve singularity which is generic in its equisingularity class. In this article we prove the conjecture for the case of two Puiseux pairs and monodromy with distinct eigenvalues. The hypothesis on the monodromy implies that the bb-exponents coincide with the opposite of the roots of the Bernstein polynomial, and we compute the roots of the Bernstein polynomial.
