Simon Telen

Postdoctoral researcher

I am a postdoctoral researcher at the Max Planck Institute for Mathematics in the Sciences at Leipzig, Germany. I am working on problems in numerical nonlinear algebra, in the Max Planck Fellow Group on Mathematical Software lead by Michael Joswig.

Research Interests

My research topics are part of a field called nonlinear algebra. This is the application-driven study of nonlinear equations, with a view towards computation. 

In my PhD research, I have developed methods for solving systems of polynomial equations numerically. The focus was on the important class of so-called 0-dimensional systems (i.e. with finitely many solutions). In some approaches such a system is reformulated as an eigenvalue problem, other algorithms solve the problem via numerical homotopy continuation.

I am particularly interested in the important role of toric geometry in the solution of systems of polynomial equations, and its applications in other fields of science.

Methods from nonlinear algebra and equation solving can be used to address mathematical questions coming from particle physics. This includes solving scattering equations for the evaluation of scattering amplitudes and computing the singularity loci of Feynman integrals.
