由~*-正则半群簇的Mal’cev积生成的簇

本文试图从泛代数的角度来研究*-正则半群．首先，我们定义了*-关系态射，讨论了它的性质；然后，用*-关系态射作为桥梁，刻划了二个*-正则半群簇的Mal’cev积生成的*-正则半群簇．特别地，我们确定了形如〈uog〉〈uoReB〉，〈uoReg〉的*-正则半群簇．

Scattering States of Schrdinger Equation under the Modified Cusp Potential

We solve the one-dimensionai time-independent Schrodinger equation in the presence of the modified Cusp potential and report the solutions in terms of the Whittaker functions. We obtain the reflection and transmission coefficients as well as the bound-state solutions in terms of the Whittaker functions. We comment on the solutions and discuss them in terms of the engaged parameters.
