Equação da onda com dissipação não efetiva dependente do tempo
Resumen
The objective of this dissertation is to construct structural representations
of the solutions to Cauchy problems for weakly dissipative wave equations below
scaling and to deduce Strichartz type estimate Lp − Lq, q ≥ 2, for the solutions and
its energy. Furthermore, we show that there is a asymptotic equivalence between
the solutions for free waves equation and the solutions for the weakly dissipative
wave equation.
