Abstract
We show that for many of the bounded generalized ridged domains of Evans and Harris, all reasonable definitions of the Neumann Laplacian coincide. In particular, this shows that the lack of discreteness of the spectrum of such Laplacians is inherent, rather than an artifact of the definition.

The -Neumann operator on (0, q)-forms (1 q n) on a bounded convex domain 0 in C n is compact if and only if the boundary of 0 contains no complex analytic (equivalently: affine) variety of dimension greater than or equal to q.
The importance of eigenvalue problems concerning the Laplacian is well documented in classical and modern literature. Finding the eigenvalues for various geometries of the domains has posed many challenges which include infinite systems of algebraic equations, asymptotic methods, integral equations
