Lifting theorems for completely positive maps

Journal of Noncommutative Geometry, 2022
We prove lifting theorems for completely positive maps going out of exact C^* -algebras, where we remain in control of which ideals are mapped into which. A consequence is, that if \mathsf X

Liftings from Lorentzian α-Sasakian manifolds to tangent bundles

Қарағанды университетінің хабаршысы. Математика сериясы
The goal of the current study is to investigate the complete lift of Lorentzian α-Sasakian manifolds to the tangent bundle TM. We also examine the complete lift of the different four types of Lorentzian αSasakian manifolds and find that (TM,gC) is an η ...
