Let us notice that the inheritance of hypercyclicity by discrete subsemigroups depends strongly on the fact that the index set is or : there are hypercyclic -semigroups of operators whose index set is a sector of the complex plane and such that no discrete subsemigroup is hypercyclic [16].
In addition, the closed-loop poles can be forced into some sector of the stable half-plane to obtain well-damped transient responses.
The parameter varies among the limits of a closed sector Q of the complex plane, with vertex at the origin of coordinates.
At the cockpit stood the Plaza of the Three Powers, and along the body of the plane, sectors for monuments, cultural centers and a chapel.
But Army sources said later today that Bedouins in the western sector of the Sinai re ported that planes crashed in the mountains late yesterday.
And as the plane passes through each sector of the airspace the controller jots down, using a kind of shorthand, everything new that is happening to the plane — its speed, say, and where it's heading, clearances from ground control, holding instructions, comments on the pilot.

Therefore, the k landmarks contained in each sector can be subdivided into b landmarks on the boundary between sectors, m landmarks on the midline of the sector (the mid-plane for 3D data), and p pairs of corresponding landmarks on either side of the midline of the sector, so that k = 2 p + b + m.
Fortunately, most of the plane was asleep.
