Description: Detailed theories of the effect of the superconductivity of Sr2 RuO4 on the velocity and on the attenuation of sound waves are developed. Two results of particular importance come out of these studies. I show that the discontinuity in the elastic constant C66  at the superconducting transition temperature implies that the superconducting order parameter in Sr2RuO4 has two components and breaks time-reversal symmetry. In addition, I show how a detailed analysis of the ultrasonic attenuation experiments performed on Sr2RuO4 leads to a new model for the superconducting gap structure of Sr2RuO 4. Its symmetry, and the details of the three-band normal-state Fermi surface of Sr2RuO4, all play important roles in these studies.
