Title: Isospectrality For Orbifold Lens Spaces,
Abstract: We answer Mark Kac's famous question, "can one hear the shape of a drum?" in
the positive for orbifolds that are 3-dimensional and 4-dimensional lens
spaces; we thus complete the answer to this question for orbifold lens spaces
in all dimensions. We also show that the coefficients of the asymptotic
expansion of the trace of the heat kernel are not sufficient to determine the
above results.
