Spectral Theory of Operators : Fourteenth School on Operators in Functional Spaces, Novgorod State Pedagogical Institute, 1989

Containing the proceedings of the Fourteenth School on Operators in Functional Spaces, this volume focuses on the spectral theory of differential operators. The emphasis is on estimates of the number of negative eigenvalues of elliptic differential operators and on the analysis of asymptotical distribution of eigenvalues. Leading Soviet specialists in this area provide an excellent overview of some of the major problems in the field.
