在$\mathbb{R}^N$中发展分数阶p-Laplacian方程.基本解与渐近性态

The evolution fractional p-Laplacian equation in $\mathbb{R}^N$. Fundamental solution and asymptotic behaviour

Juan Luis Vázquez

摘要:

本文研究了在整个欧几里得空间中自然存在的含时分数阶$p$方程,其参数为$p>2$和$s\in (0,1)$(分数阶指数).我们证明了Lebesgue $L^q$空间中数据的Cauchy问题是适定的,并且证明了这些解形成了一族具有正则性和其他有趣性质的非扩张半群。作为主要结果,我们对每个质量值$M,$构造了自相似基本解,并证明了一般有限质量解在所有$L^q$空间中收敛于具有相同质量的基本解.

英文摘要:

We consider the natural time-dependent fractional $p$-Laplacian equation posed in the whole Euclidean space, with parameters $p>2$ and $s\in (0,1)$ (fractional exponent). We show that the Cauchy Problem for data in the Lebesgue $L^q$ 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 $M,$ and prove that general finite-mass solutions converge towards that fundamental solution having the same mass in all $L^q$ spaces.A number of additional properties and estimates complete the picture.
