Dunkl wave equation方程解的$L^p-L^q$估计

$L^p-L^q$ estimates for the solution of the Dunkl wave equation

Béchir Amri, Mohamed Gaidi

摘要:

本文的主要目的是导出齐次线性波动方程Cauchy问题解的$u_k(x,t)$(t固定)的$L^p-L^q$估计,$Δ_k$,$$Δ_ku_k(x,t)= \partial_t^2u_k (x,t),\quad \partial_tu_k(x,0)= f(x),\quad u_k(x,0)= g(x).$$。我们将Srichartz在\cite{Sti}中给出的常值波动方程的估计推广到Dunkl。

英文摘要:

In this paper, our main aim is to derive $L^p-L^q$ estimates of the solution $u_k(x,t)$ ( t fixed) of the Cauchy problem for the homogeneous linear wave equation associated to the Dunkl Laplacian $Δ_k$, $$Δ_ku_k(x,t)= \partial_t^2u_k (x,t),\quad \partial_tu_k(x,0)= f(x),\quad u_k(x,0)= g(x).$$ We extend to Dunkl setting the estimates given by Srichartz in \cite{Sti} for the ordinary wave equation .
