This page hosts information on Kathlén Kohn's talk "What is … an Eigenvector of a Tensor?" at the "What is …?" seminar. This talk will help you better understand the talk by Bernd Sturmfels.
This talk gives an introduction to tensors and their eigenvectors. It is especially addressed to people that are not algebraists. We will see that tensors and their eigenvectors appear naturally when using Lagrange-multipliers in optimization and when studying higher order Markov chains in stochastics.
