系数在时间变量上可测的抛物型方程的Hörmander定理

Hörmander's theorem for parabolic equations with coefficients measurable in the time variable

N. V. Krylov

摘要:

我们正在处理可能退化的二阶抛物型算子的系数是无限可微的空间变量和仅测量的时间变量。我们将Hörmander条件加在扩散系数上,证明了在空间-时域中关于空间变量的右端无穷可微的相应方程的解也具有这一性质.

英文摘要:

We are dealing with possibly degenerate second-order parabolic operators whose coefficients are infinitely differentiable with respect to space variables and only measurable with respect to the time variable. We impose the Hörmander condition on the diffusion coefficients and prove that the solutions of the corresponding equations with right-hand sides which are infinitely differentiable in the space variables in a space-time domain have also this property.
