摘要:

本文研究了带变指数的非局部变分泛函极小元,以及对应欧拉-拉格朗日(Euler–Lagrange)方程弱解的局部正则性性质。我们证明,当变指数$p$仅满足连续且有界的条件时,弱解是局部有界的。此外,我们还证明,在对$p$施加一些额外假设的条件下,有界弱解是局部赫尔德(Hölder)连续的。一方面,容许指数类需在区域内满足对数赫尔德型条件,这一条件即便在局部方程的情形下也至关重要。另一方面,由于我们研究的是非局部问题,需要对区域外的$p$施加额外假设。

英文摘要:

In this paper, we study local regularity properties of minimizers of nonlocal variational functionals with variable exponents and weak solutions to the corresponding Euler--Lagrange equations. We show that weak solutions are locally bounded when the variable exponent $p$ is only assumed to be continuous and bounded. Furthermore, we prove that bounded weak solutions are locally Hölder continuous under some additional assumptions on $p$. On the one hand, the class of admissible exponents is assumed to satisfy a log-Hölder-type condition inside the domain, which is essential even in the case of local equations. On the other hand, since we are concerned with nonlocal problems, we need an additional assumption on $p$ outside the domain.
