**Abstract:** There has been a good deal of progress on
eigenvalue problems, such as the problem of characterizing the
possible eigenvalues of three Hermitian matrices, when one is the sum
of the other two. The solutions relate this problem to that of
enumerating intersections in Grassmannians, a classical subject in
algebraic geometry known as Schubert calculus. This work has led to
new insights in Schubert calculus as well. We will discuss this
problem, as well as some recent variations.
