Roots and Logarithms of Multipliers

Jingbo Xia, Congquan Yan, Danjun Zhao +1

By now it is a well-known fact that if $f$ is a multiplier for the Drury-Arveson space $H_{n}^{2}$ , and if there is a $c > 0$ such that $∣ f (z) ∣ \geq c$ for every $z \in B$ , then the recipr…

Derivations, local and 2-local derivations on some algebras of operators on Hilbert C*-modules

Jun He, Jiankui Li, Danjun Zhao

For a commutative C*-algebra $A$ with unit $e$ and a Hilbert~ $A$ -module $M$ , denote by End $_{A} (M)$ the algebra of all bounded $\mathca…
