We consider the natural time-dependent fractional -Laplacian equation posed in the whole Euclidean space, with parameters and (fractional exponent). We show that the Cauchy Problem for data in the Lebesgue spaces is well posed, and show that the solutions form a family of non-expansive semigroups with regularity and other interesting properties. As main results, we construct the self-similar fundamental solution for every mass value and prove that general finite-mass solutions converge towards that fundamental solution having the same mass, and convergence holds in all spaces. A number of additional properties and estimates complete the picture.

演化分数p-Laplacian方程 。基本解和渐近行为
我们考虑自然时间相关的分数 -拉普拉斯方程在整个欧氏空间中构成,其参数 和 (分数指数)。我们证明了Lebesgue中数据的柯西问题空间的位置很好,表明这些解形成了一个具有规则性和其他有趣性质的非扩展半群族。作为主要结果,我们为每个质量值构造了自相似的基本解 并证明一般的有限质量解收敛于具有相同质量的基本解,并且收敛在所有 空格。许多其他属性和估计值可以完成整个过程。
