Tóm tắt:

Prony proposed 1795 a method to solve the parameter reconstruction problem for exponential sums in the univariate case. The key idea is to consider an associated polynomial equation and to study an equivalent algebraic problem. In this talk we present a generalization of Prony’s method to the multivariate case. We discuss related algebraic problems and methods. The talk is based on joint work with Stefan Kunis, Thomas Peter and Ulrich von der Ohe.
