On the single layer boundary integral operator for the Dirac equation

Markus Holzmann

AI总结:

本文分析了二维和三维下狄拉克方程的单层边界积分算子$\mathcal{C}_z$的映射性质与正负部分解,结果可用于处理含临界组合奇异相互作用的狄拉克算子。

摘要:

本文致力于分析二维和三维情形下狄拉克方程的单层边界积分算子$\u2006\mathcal{C}_z$。映射$\mathcal{C}_z$是带有自由狄拉克算子$A_0$预解式积分核的强奇异积分算子,且$z$属于$A_0$的预解集。在光滑边界的情形下,本文分析了$\mathcal{C}_z$的精细映射性质以及其“正”部与“负”部的分解。所得结果可应用于处理以临界方式结合的奇异静电相互作用、洛伦兹标量相互作用和反常磁相互作用的狄拉克算子。

英文摘要:

This paper is devoted to the analysis of the single layer boundary integral operator $\mathcal{C}_z$ for the Dirac equation in the two- and three-dimensional situation. The map $\mathcal{C}_z$ is the strongly singular integral operator having the integral kernel of the resolvent of the free Dirac operator $A_0$ and $z$ belongs to the resolvent set of $A_0$. In the case of smooth boundaries fine mapping properties and a decomposition of $\mathcal{C}_z$ in a 'positive' and 'negative' part are analyzed. The obtained results can be applied in the treatment of Dirac operators with singular electrostatic, Lorentz scalar, and anomalous magnetic interactions that are combined in a critical way.
