On the existence of eigenvalues of Toeplitz operators on planar regions
2004
Proceedings of the American Mathematical Society
Preserved Fulltext
A study is made of the eigenvalues of self-adjoint Toeplitz operators on multiply connected planar regions having g holes. The presence of eigenvalues is detected through an analysis of the zeros of translations of theta functions restricted to R g in C g .
