On the eigenvalues of the rhombical membrane
In this paper both upper bounds and lower bounds are given for the first eigenvalues of a rhombical membrane with free boundary. The upper bounds are obtained through an application of the Rayleigh-Ritz method. The lower bounds are calculated by means of a procedure relying on the Orthogonal Invaria...
