Title: Solution of a spectral problem for the curl operator on a cylinder Authors: Romen Saks (Bashkir State Univ., Ufa, Russia) Carmen Judith Vanegas (Univ. Simon Bolivar, Miranda, Venezuela) Abstract: In this work, we give method to construct an explicit solutions to one spectral problem with the curl operator on a bounded cylinder. The eigen-values of this operator are square roots of eigen-values of Laplace operator (with Dirichlet boundary condition) and zero. The eigen-functions related to this problem are found using some results from complex analysis. Published May 30, 2005. Math Subject Classifications: 35P05, 35J25, 35J55.
