The quadratic formula learned by generations of math students is difficult to remember, but it can be used to solve quadratic equations where y = 0.

We provide a theory for the analysis of multigrid algorithms for symmetric positive definite problems with nonnested spaces and noninherited quadratic forms. By this we mean that the form on the ...
