On the spectra of Schrödinger and Jacobi operators with complex-valued quasi-periodic algebro-geometric coefficients
(University of Missouri--Columbia, 2005)In this thesis we characterize the spectrum of one-dimensional Schrödinger operators. H = -d2/dx2+V in L2(R; dx) with quasi-periodic complex-valued algebro geometric, potentials V (i.e., potentials V which satisfy one ... -
Topics in spectral and inverse spectral theory
(University of Missouri--Columbia, 2006)This dissertation is concerned with two major classes of operators and provides various spectral and inverse spectral results for them. In the first part of this work a special class of one-dimensional discrete unitary ... -
Topics in spectral theory of differential operators /
(University of Missouri--Columbia, 2017)This dissertation is devoted to two eigenvalue counting problems: Determining the asymptotic behavior of large eigenvalues of self-adjoint extensions of partial differential operators, and computing the number of negative ...
