We establish the higher fractional differentiability of the solutions of a problem in divergence form of the type
div A ( x , D u ) = div | F | p ( x ) 2 2 F in Ω , u = 0 on Ω .
The main features consist in assuming that the partial map ξ A ( x , ξ ) has p ( x ) ‐growth, the datum F is Besov regular and both the partial map x A ( x , ξ ) and the function x p ( x ) are Orlicz–Besov regular.

具有可变指数的椭圆型方程解的Besov正则性

我们以类型的散度形式建立问题解的较高分数微分性
div 一种 X d ü = div | F | p X - 2 2 F Ω ü = 0 Ω
主要特征在于假设局部地图 ξ 一种 X ξ 具有 p X 增长时,基准面F是Besov正则,且均为局部图 X 一种 X ξ 和功能 X p X 是Orlicz–Besov的常客。
