平面上非一致椭圆积分泛函的Lipschitz界

Lipschitz bounds for nonuniformly elliptic integral functionals in the plane

Mathias Schäffner

AI总结:

该研究针对二维平面带受控$(p,q)$增长的标量积分泛函局部极小元的正则性问题,将Lipschitz连续性成立的条件从经典的$q<2p$放宽至$q<3p$,同时得到了平面线性一致椭圆方程解的最优$L^\infty$-$L^2$估计。

摘要:

我们研究了二维平面上具有受控$(p,q)$增长的标量积分泛函局部极小元的局部正则性性质。我们在$1<p\leq q<\infty$且$q<3p$的条件下建立了局部极小元的Lipschitz连续性,这一结果改进了仅在$q<2p$范围内成立的经典结果。在此过程中,我们还建立了平面上线性一致椭圆方程解的$L^\infty$-$L^2$估计,该估计关于系数的椭圆性对比度是最优的。

英文摘要:

We study local regularity properties of local minimizer of scalar integral functionals with controlled $(p,q)$-growth in the two-dimensional plane. We establish Lipschitz continuity for local minimizer under the condition $1<p\leq q<\infty$ with $q<3p$ which improve upon the classical results valid in the regime $q<2p$. Along the way, we establish an $L^\infty$-$L^2$-estimate for solutions of linear uniformly elliptic equations in the plane which is optimal with respect to the ellipticity contrast of the coefficients.
