I will discuss some recent results on developing new factorizations
for matrices obtained from discretizing differential and integral
operators. A common ingredient of these new factorizations is the
interpolative decomposition for numerically low-rank matrices. As we
shall see, these factorizations offer efficient algorithms for
applying and inverting these operators. This is a joint work with
Kenneth Ho.
