|Buser, Conway, Doyle, Semmler|
|A paper on isospectral pairs of plane domains, and a particularly simple method of proving isospectrality. One example is a pair of domains that are not only isospectral but homophonic, showing that one really can't hear the shape of a drum. With a gallery of examples, Mathematica notebooks of figures and further examples.|
