Numerical comparison of negative damping bounds in a specified domain when the wave speed varies
(IEEE, 1992-06-24)The energy decay of a self-excited wave equation utt - c2 ¿ u - P(x)ut = 0 is studied where the wave speed c is greater than one, P(x) ¿ 0, and P(x) L¿(¿), ¿ ¿ ¿ Rn. Moreover, the relationship between two bounds for ... -
