Vladimir Maz'ya, Robert McOwen

摘要:

对一类散度型二阶椭圆型方程,研究了其所有解在给定点处Lipschitz连续或可微的系数条件.我们假设系数的连续模满足平方-迪尼条件,并得到额外的条件,例子表明是尖锐的。我们的结果扩展了以前的作者谁假设的连续模满足Dini条件。我们的方法涉及到一个动力系统的解的渐近性质的研究,该动力系统是由椭圆型方程的系数。

英文摘要:

For a second-order elliptic equation in divergence form we investigate conditions on the coefficients which imply that all solutions are Lipschitz continuous or differentiable at a given point. We assume the coefficients have modulus of continuity satisfying the square-Dini condition, and obtain additional conditions that examples show are sharp. Our results extend those of previous authors who assume the modulus of continuity satisfies the Dini condition. Our method involves the study of asymptotic properties of solutions to a dynamical system that is derived from the coefficients of the elliptic equation.
