Can't one really hear the shape of a drum?
Abbreviated Journal Title
eigen states; eigen values; Fourier transform; EQUATIONS; Acoustics
In this paper we study the wave and the Klein-Gordon equations in frontiers with the same set of eigen values using a computational algorithm based on the finite difference method and the discrete Fourier transform. Doing this we found that although the set of eigen values in the two shapes are equal, the intensities in the spectrum are different, which means that the question, can one hear the shape of a drum? is still open.
