The generalized polar decomposition, the weak complementarity and the parallel sum for adjointable operators on Hilbert $C^{\ast }$-modules

Xiaofeng Zhang, Xiaoyi Tian, Qingxiang Xu

This paper deals mainly with some aspects of the adjointable operators on Hilbert $C^{\ast }$-modules. A new tool called the generalized polar decomposition for each adjointable operator…
