Abstract: A GL-variety is an infinite-dimensional variety equipped with a suitable action of the infinite-dimensional general linear group. GL-varieties arise naturally in the study of properties of polynomials (and more general tensors) that do not depend on their number of variables, a research theme that is attracting attention in diverse areas of mathematics. I will report on joint work with Arthur Bik, Alessandro Danelon, Rob Eggermont, and Andrew Snowden, in which we establish GL-analogues of several fundamental theorems on finite-dimensional varieties.
