DESCRIPTION:Abstract: The admissible numerator problem is the following: gi
ven a polynomial p with no zeros on some domain D, describe all polynomia
ls q such that q/p is bounded on D. Joint work with Bickel, Pascoe, Sola
along with a paper by Kollar solved the admissible numerator problem for
the bidisk by converting it to a local problem in the context of the bi-up
per half plane. A key tool was understanding Puiseux expansions for stabl
e polynomials. Recently we have extended some elements of this theory to
the unit ball in C^2, where the Puiseux series behave very differently,
as well as to special cases in the tri-disk where Puiseux series are unava
ilable. In particular, the case of p having a smooth point of its zero s
et intersecting the 3-torus becomes tractable. \n\nHost: Walton Green
