Query: Eigenvalue bounds for a class of Schroedinger operators in a strip   This paper is concerned with the estimation of the number of negative
eigenvalues (bound states) of Schroedinger operators in a strip subject to
Neumann boundary conditions. The estimates involve weighted L^1 norms and L ln
L norms of the potential. Estimates involving the norms of the potential
supported by a curve embedded in the strip are also presented.
