Dirac算子的预解估计

Resolvent estimates of the Dirac operator

Chris Pladdy, Yoshimi Saito, Tomio Umeda

摘要:

我们将研究Dirac算子的扩展预解式R(s)随着|s|增加到无穷大的渐近行为,其中s是实参数.证明了R(s)作为三维欧几里得空间上平方可积〔的〕函数的两个加权希尔伯特空间之间的有界算子的范数是有界的。我们还将证明当|s|增加到无穷大时,R(s)强收敛于0。这个结果和Yamada [15]的结果结合起来表明Dirac算子的扩展预解式比Schroedinger算子的扩展预解式衰减得慢得多。

英文摘要:

We shall investigate the asymptotic behavior of the extended resolvent R(s) of the Dirac operator as |s| increases to infinity, where s is a real parameter. It will be shown that the norm of R(s), as a bounded operator between two weighted Hilbert spaces of square integrable functions on the 3-dimensional Euclidean space, stays bounded. Also we shall show that R(s) converges 0 strongly as |s| increases to infinity. This result and a result of Yamada [15] are combined to indicate that the extended resolvent of the Dirac operator decays much more slowly than those of Schroedinger operators.
