Theorem 7 imposes a quantitative restriction on the location of the zeros of......
However, if B were omitted in (1), the case n=0 would imply Nf=1, an undesirable restriction.
Some restrictions must be placed on the behaviour of f.
This theorem removes the restriction to convex regions which was imposed in Theorem 8.
All our estimates hold without this restriction.
The location of the zeros of a holomorphic function in a region Ω is subject to no restriction except the obvious one concerning the absence of limit points in Ω.
