Elliptic Problems Involving an Indefinite Weight
Elliptic Problems Involving an Indefinite Weight
We consider a selfadjoint elliptic eigenvalue problem, which is derived formally from a variational problem, of the form Lu = AW(X)U in n, Bju = 0 on r, j = I, ... , m, where L is a linear elliptic operator of order 2m defined in a bounded open set …
