具有不规则势的退化薛定谔方程

Degenerate Schrödinger equations with irregular potentials

Duván Cardona, Marianna Chatzakou, Julio Delgado, Michael Ruzhansky

摘要:

本文通过引入合适的Hörmander度量$g$和$g$ -权$m$,研究了一类与$\Ran$上具有非正则位势的退化椭圆算子相关的退化薛定谔方程.我们建立了相应的退化薛定谔方程和退化抛物方程的适定性。当亚椭圆性在退化椭圆算子上成立时,我们导出了一类退化Hamilton算子的谱性质。我们还本着经典Fefferman的$L^p$-$(ρ, δ)$演算界限的精神,研究了带有$S(m^{-β},g)$类中符号的运算符的$L^p$映射属性。最后,在我们的$S(m,g)$类,尖锐的$L^p$ -估计和Schatten性质的薛定谔算子的Hörmander平方和进行了研究。

英文摘要:

In this work we investigate a class of degenerate Schrödinger equations associated to degenerate elliptic operators with irregular potentials on $\Ran$ by introducing a suitable Hörmander metric $g$ and a $g$-weight $m$. We establish the well-posedness for the corresponding degenerate Schrödinger and degenerate parabolic equations. When the subelliticity is available on the degenerate elliptic operator we deduce spectral properties for a class of degenerate Hamiltonians. We also study the $L^p$ mapping properties for operators with symbols in the $S(m^{-β},g)$ classes in the spirit of classical Fefferman's $L^p$-bounds for the $(ρ, δ)$ calculus. Finally, within our $S(m,g)$-classes, sharp $L^p$-estimates and Schatten properties for Schrödinger operators for Hörmander sums of squares are also investigated.
