Numerically robust computation of circular visibility
Stephan Brummer, Georg Maier, Tomas Sauer
We address the question of whether a point inside a domain bounded by a simple closed arc spline is circularly visible from a specified arc from the boundary. We provide a simple a…
Observations on interpolation by total degree polynomials in two variables
Jesús Carnicer, Tomas Sauer
In contrast to the univariate case, interpolation with polynomials of a given maximal total degree is not always possible even if the number of interpolation points and the space d…
Prony's method in several variables: symbolic solutions by universal interpolation
Tomas Sauer
The paper considers a symbolic approach to Prony's method in several variables and its close connection to multivariate polynomial interpolation. Based on the concept of universal…
Prony's method in several variables
Tomas Sauer
The paper gives an extension of Prony's method to the multivariate case which is based on the relationship between polynomial interpolation, normal forms modulo ideals and H--bases…
