Title: Eigenvalues of sums of matrices: Singular values and invariant factors

Abstract: There are questions about singular values and invariant factors for products of matrices (scalar or over more complicated rings) that can be answered using the elementary intersection theory discussed in the second lecture. We show how one can use intersection theory to produce invariant subspaces with specified properties, for instance, for linear operators on a finite dimensional space.
