Geometry of tensor network varieties

Tensor network varieties are varieties of tensors described by the combinatorial structure of a graph. They play a major role in quantum many-body physics as well as in other areas of applied mathematics, such as algebraic complexity theory and algebraic statistics.
In this seminar, I will introduce tensor network varieties, focusing on their geometric structure. I will show how to study their dimension, equations, and special subvarieties of interest.
