Strategic vertical integration calls for a broader mandate. It means integrating upstream suppliers and downstream service ...

Let Ω α be the asymmetrical vertical strips defined by Ω α = {ω : α − π 2 sin α < Re ω < α 2 sin α}, where π / 2 ≤ α < π, and let 픻 be the unit disk. We characterize the class S H 픻, Ω α) of univalent ...
