摘要:

本文研究完全非线性障碍问题的全局解。我们证明,在剔除不变方向后,任何全局解的重合集属于以下四类之一:单点、内部非空的紧凸集、n=1时的射线,或n≥2时的细长体,其中n表示空间维数。此外,我们建立了具有紧重合集的所有全局解构成的集合与描述此类解在无穷远处渐近行为的函数族之间的双射关系。

英文摘要:

In this paper, we investigate global solutions to the fully nonlinear obstacle problem. We prove that, after factoring out invariant directions, the coincidence set of any global solution belongs to one of the following four types: a single point, a compact convex set with nonempty interior, a ray for $n=1$, or a slender body for $n\geq 2$, where $n$ denotes the spatial dimension. Furthermore, we establish a bijection between the collection of all global solutions with compact coincidence sets and a family of functions describing the asymptotic behavior of such solutions at infinity.
