Critical exponent wiki
WebIn this paper we solve the critical exponent problem for the wave Eq. (1.1), (1.2) which involves not only a source but also a linear damping term. We show that the influence of the damping is powerful enough to shift the critical exponent p 0 (n) of the wave equation to the left, i.e. the critical exponent p c (n) for Eq. (1.1) is strictly ...
