摘要

bαp(R+1+n)b_{\alpha}^{p}(\mathbb{R}^{1+n}_{+})为抛物型方程tu+()αu=0\partial_{t}u+(-\triangle)^{\alpha}u=0 (α(0,1])(\alpha\in(0, 1])的解空间,其具有有限的Lp(R+1+n)L^{p}(\mathbb{R}^{1+n}_{+})范数。我们刻画了R+1+n\mathbb{R}^{1+n}_{+}上具有性质uLq(R+1+n,μ)uW˙1,p(R+1+n),\|u\|_{L^{q}(\mathbb{R}^{1+n}_{+},\mu)}\lesssim \|u\|_{\dot{W}^{1,p}(\mathbb{R}^{1+n}_{+})}, 1pq<,1\leq p\leq q<\infty, 的非负Radon测度μ\mu,其中u(t,x)bαp(R+1+n)W˙1.p(R+1+n)u(t,x)\in b_{\alpha}^{p}(\mathbb{R}^{1+n}_{+})\cap \dot{W}^{1.p}(\mathbb{R}^{1+n}_{+})。同时,记v(t,x)v(t,x)为上述方程以Cauchy数据v0(x)v_{0}(x)的解,我们刻画了R+1+n\mathbb{R}_{+}^{1+n}上满足v(t2α,x)Lq(R+1+n,μ)v0W˙β,p(Rn),\|v(t^{2\alpha},x)\|_{L^{q}(\mathbb{R}_{+}^{1+n}, \mu)}\lesssim\|v_{0}\|_{\dot{W}^{\beta,p}(\mathbb{R}^{n})}, β(0,n),\beta\in (0,n), p[1,n/β],p\in [1, n/\beta], q(0,)q\in(0, \infty)的非负Radon测度μ\mu。此外,我们得到了v(t,x)v(t,x)的衰减、一个等容不等式和一个迹不等式。
