积分-微分算子解的解析性

Analyticity for Solution of Integro-Differential Operators

Simon Blatt

摘要:

证明了对于一类核函数$K(y)$,当$f$是解析函数时,积分微分方程$$ \int_{\mathbb R^n} (u(x+y) - 2 u(x) + u(x-y)) K(y) dy = f(x,u(x)) $$的黏性解是局部解析的.这扩展了Albanese,Fiscella,Valdinoci的结果,这种解决方案属于某些Gevrey类。

英文摘要:

We prove that for a certain class of kernels $K(y)$ that viscosity solutions of the integro-differential equation $$ \int_{\mathbb R^n} (u(x+y) - 2 u(x) + u(x-y)) K(y) dy = f(x,u(x)) $$ are locally analytic if $f$ is an analytic function. This extends the result of Albanese, Fiscella, Valdinoci that such solutions belong to certain Gevrey classes.
