Abstract
In this article we discuss the notion of $\gamma $-$H^{\infty }$-bounded calculus, $\gamma $-$m$-$H^{\infty }$-bounded calculus on a half-plane and the weak-$\gamma $ Gomilko–Shi–Feng condition and give a connection between them. Then we state a characterization of generation of a $\gamma $-bounded $C_0$-semigroup in a $K$-convex space, which leads to a version of Gearhart–Prüss on $K$-convex spaces.
