摘要
在本文中,我们证明整个欧氏空间上演化方程的Barenblatt解的存在性与唯一性,其中主部为与幂函数复合的非局部分数阶p-Laplacian。我们的证明推广了J.-L. Vazquez [Nonlinear Anal., 199 (2022), Calc. Var. Partial Differential Equations, 60 (2021)] 针对整个欧氏空间上由分数阶p-Laplacian驱动的演化方程所发展的方法。特别地,我们需要一个Aleksandrov对称原理,该原理可应用于由双非线性非局部算子驱动的中演化方程的温和解,以及全局障碍函数的构造。Aleksandrov对称原理本身可能具有独立意义。
