Sharp spectral asymptotics and Weyl formula for elliptic operators with Non-smooth Coefficients–-Part 2
Lech Zieliński · Colloquium Mathematicum · 2002
We describe the asymptotic distribution of eigenvalues of self-adjoint elliptic differential operators, assuming that the first-order derivatives of the coefficients are Lipschitz continuous. We consider the asymptotic formula of Hörmander's type for the
