摘要

在本文中，具有一般δ $\ δ $壳层势的Dirac算子在r2 $\mathbb {R}^2$或c2 $C^2$曲线上的近似研究了r3 $\mathbb {R}^3$中的c2 $C^2$ -曲面，它可以是有界的，也可以是无界的。在δ $\ δ $ -相互作用权值的适当条件下，具有正则压缩势的狄拉克算子族在范数解析意义上收敛于具有δ $\ δ $ -壳相互作用的狄拉克算子族。

Approximation of Dirac operators with δ ${\delta }$ -shell potentials in the norm resolvent sense. I. Qualitative results

In this paper, the approximation of Dirac operators with general $δ$ -shell potentials supported on $C^{2}$ -curves in $R^{2}$ or $C^{2}$ -surfaces in $R^{3}$ , which may be bounded or unbounded, is studied. It is shown under suitable conditions on the weight of the $δ$ -interaction that a family of Dirac operators with regular, squeezed potentials converges in the norm resolvent sense to the Dirac operator with the $δ$ -shell interaction.
