Group varieties of polynomials and computational complexity

Many varieties of polynomials carry a canonical action of the general linear group. This talk gives an introduction on how representation theory can be used in the study of the equations of such varieties. We then focus on recent research in geometric complexity theory on continuant orbit closures and plethysm coefficients.
