| Abstract: | In this paper we give a lower bound for the first eigenvalue of an ordinary differential operator which represents the radial part of the Laplace operator restricted to a spherical cap of a sphere, possibly of fractional dimension. The results are obtained by purely analytical methods.Research supported by CONICIT. |
