一类中曲率方程极值解的存在性和正则性

Existence and regularity of extremal solutions for a mean-curvature equation

Antoine Mellet, Julien Vovelle

摘要:

研究了一类平均曲率方程$-\mathcal Mu=H+λu^p$,其中$\mathcal M$表示平均曲率算子,对于$p\geq 1$ .我们证明了存在极值参数$λ^*$使得该方程对所有$λ\in [0,λ^*]$都存在极小弱解,而对$λ>λ^*$不存在弱解(弱解定义为适当泛函的临界点).在径向对称的情况下,我们证明了最小弱解是所有$λ\in [0,λ^*]$的经典解,并且经典解的另一个分支存在于$λ^*$的邻域$(λ_*-η,λ^*)$中。

英文摘要:

We study a class of mean curvature equations $-\mathcal Mu=H+λu^p$ where $\mathcal M$ denotes the mean curvature operator and for $p\geq 1$. We show that there exists an extremal parameter $λ^*$ such that this equation admits a minimal weak solutions for all $λ\in [0,λ^*]$, while no weak solutions exists for $λ>λ^*$ (weak solutions will be defined as critical points of a suitable functional). In the radially symmetric case, we then show that minimal weak solutions are classical solutions for all $λ\in [0,λ^*]$ and that another branch of classical solutions exists in a neighborhood $(λ_*-η,λ^*)$ of $λ^*$.
