薛定谔方程的最小支集结果

Minimal support results for Schrödinger equations

Laura De Carli, Julian Edward, Steve Hudson, Mark Leckband

摘要:

本文考虑了一类广义薛定谔方程的线性和非线性边值问题。模型实例是$u\in W_0^{1,2}(D)$的$-Δu=Vu$,其中$D$是${\bf R^n}$中的有界域。利用Sobolev嵌入定理,在某些情况下利用Moser-Trudinger不等式和Hardy-Sobolev不等式,得到了非平凡解存在的必要条件.这些条件通常涉及$V$的范数的幂的乘积的下界、$D$的测度和尖锐的Sobolev常数。在大多数情况下,这些不平等是最好的。

英文摘要:

We consider a number of linear and non-linear boundary value problems involving generalized Schrödinger equations. The model case is $-Δu=Vu$ for $u\in W_0^{1,2}(D)$ with $D$ a bounded domain in ${\bf R^n}$. We use the Sobolev embedding theorem, and in some cases the Moser-Trudinger inequality and the Hardy-Sobolev inequality, to derive necessary conditions for the existence of nontrivial solutions. These conditions usually involve a lower bound for a product of powers of the norm of $V$, the measure of $D$, and a sharp Sobolev constant. In most cases, these inequalities are best possible.
