摘要
We prove a generalization of the Strichartz estimate for the inhomogeneous wave equation square u(t, x) = f (t, x) in the space-time Rl+n. We estimate the solution in vector-valued homogeneous Besov spaces (B) over dot(q,2)(theta) (R; (B) over dot(r,2)(sigma) (R-n)). Such an estimate shows the time differentiability of the solution of fractional order.
