Abstract
We investigate the existence of principal eigenvalues (i.e., eigenvalues co rresponding to positive eigenfunctions) for the boundary value problem -Del ta u(x) = lambda g(x)u(x) on D; partial derivative u/partial derivative u(x ) + alpha u(x) = 0 on partial derivative D, where D is a bounded region in R-N, g is an indefinite weight function and alpha is an element of R may be positive, negative or zero.
