抽象的。对于狄拉克算子 $ {\Bbb R}^3 $,具有无穷大的电势,就像 |x| 的幂一样,我们证明了共振的存在,并且我们研究了,当 $ c \rightarrow + \infty $,其实部的渐近展开,以及其虚部的估计,概括了 Titchmarsh 的旧结果。
Abstract. For a Dirac operator in $ {\Bbb R}^3 $, with an electric potential behaving at infinity like a power of |x|, we prove the existence of resonances and we study, when $ c \rightarrow + \infty $, the asymptotic expansion of their real part,and an estimation of their imaginary part, generalizing an old result of Titchmarsh.
