$k$-Hessian 方程的一个梯度型项

A gradient type term for the $k$-Hessian equation

Mykael de Araújo Cardoso, Jefferson de Brito Sousa, José Francisco de Oliveira

AI总结:

本文为 $k$-Hessian 方程构造了推广经典二次梯度项的梯度型项,证明其 Kazdan-Kramer 变换不变性,并据此在 Sobolev 型增长及 Trudinger-Moser 型增长的次临界与临界条件下建立解的存在性。

摘要:

本文为 $k$-Hessian 方程提出了一个梯度型项,它将与 Laplace 方程相关的经典二次梯度项推广到 $k>1$ 的情形。我们证明了该梯度项在 Kazdan-Kramer 变量变换下保持不变。作为应用,我们确保了一类新的 $k$-Hessian 方程在 Sobolev 型增长的次线性和超线性情形下解的存在性。在某些特殊情形下得到了存在性的阈值。此外,对于 Trudinger-Moser 型增长机制,我们也在次临界或临界条件下证明了解的存在性。

英文摘要:

In this paper, we propose a gradient type term for the $k$-Hessian equation that extends for $k>1$ the classical quadratic gradient term associated with the Laplace equation. We prove that such as gradient term is invariant by the Kazdan-Kramer change of variables. As applications, we ensure the existence of solutions for a new class of $k$-Hessian equation in the sublinear and superlinear cases for Sobolev type growth. The threshold for existence is obtained in some particular cases. In addition, for the Trudinger-Moser type growth regime, we also prove the existence of solutions under either subcritical or critical conditions.
