The calculation of the frequencies ω for small oscillations of an ideal liquid in a container results in a Steckloff eigenvalue problem. A procedure for calculating lower and upper bounds to the smallest eigenvalues is proposed. For the lower bound computation Goerisch’s generalization of Lehmann’s method is applied, trial functions are constructed with finite elements. Rounding errors are controlled with interval arithmetic.
