关于$L^p$ -空间中薛定谔系统的多项式标量扰动

On a polynomial scalar perturbation of a Schrödinger system in $L^p$-spaces

Abdallah Maichine, Abdelaziz Rhandi

摘要:

本文研究了矩阵薛定谔算子$\mathcal{L}u=div(Q\nabla u)+Vu$的$L^p$ -实现.在$L^p(\R^d,\C^m)$中半群的生成和结构域$D(L_p)$的特征已经建立。本文用一个包含所有多项式的标量位扰动算子$L_p$,证明了在$L^p(\R^d,\C^m)$上仍有一个强连续半群,其整环嵌入在$W^{2,p}(\R^d,\C^m)$中.我们还研究了该半群的解析性、紧性、正性和超压缩性,并证明了高斯核估计。进一步研究了矩阵薛定谔算子特征值的核估计和渐近行为。

英文摘要:

In the paper \cite{KLMR} the $L^p$-realization $L_p$ of the matrix Schrödinger operator $\mathcal{L}u=div(Q\nabla u)+Vu$ was studied. The generation of a semigroup in $L^p(\R^d,\C^m)$ and characterization of the domain $D(L_p)$ has been established. In this paper we perturb the operator $L_p$ of by a scalar potential belonging to a class including all polynomials and show that still we have a strongly continuous semigroup on $L^p(\R^d,\C^m)$ with domain embedded in $W^{2,p}(\R^d,\C^m)$. We also study the analyticity, compactness, positivity and ultracontractivity of the semigroup and prove Gaussian kernel estimates. Further kernel estimates and asymptotic behaviour of eigenvalues of the matrix Schrödinger operator are investigated.
