c-numerical range of operator products on B(H)
Yanfang Zhang, Xiaochun Fang
Let H be a complex Hilbert space of dimension no less than 2 and B(H) be the algebra of all bounded linear operators on H. We give the form of surjective maps on B(H) preserving c-…

Characterizing derivations for any nest algebras on Banach spaces by their behaviors at an injective operator
Yanfang Zhang, Jinchuan Hou, Xiaofei Qi
Let be a nest on a complex Banach space and let $\mbox{ Alg}{\mathcal N}$ be the associated nest algebra. We say that an operator $Z\in \mbox{ Alg}{\mathcal N}$…
