Stability and hyperbolicity of polynomials and entire functions

Research team

Main areas:

Specific problems of interest include zero localization of polynomials and entire function, in one and many variables, connections with orthogonal polynomials and special functions, total positivity and oscillatory properties of operators, related eigenvalue problems, bifurcation problems in fluid mechanics, partition functions of statistical mechanics, multiplier sequences, Laguerre-Polya class.


AIM Workshop:

Petter Branden, George Csordas, Olga Holtz, and Mikhail Tyaglov organized the workshop Stability, hyperbolicity, and zero localization of functions at the American Institute of Mathematics in December 2011.
