微分表达式$${L_m=-\partial_x^2+(m^2-1/4)x^{-2}}$$当m2 ≥ 1时以自然的方式定义了L2(0,∞)上的自伴算子Hm。我们研究了Hm对参数m的依赖性,证明了它对半平面Re m > −1有唯一的全纯扩张,并分析了这类算子的谱性质和散射性质.
The differential expression $${L_m=-\partial_x^2+(m^2-1/4)x^{-2}}$$ defines a self-adjoint operator Hm on L2(0, ∞) in a natural way when m2 ≥ 1. We study the dependence of Hm on the parameter m show that it has a unique holomorphic extension to the half-plane Re m > −1, and analyze spectral and scattering properties of this family of operators.
