GROUP FOR WHICH A GIVEN GROUP IS A NORMAL SUBGROUP

Extension problem; Extension (algebra); Split extension; Extension of a group; Central extension (mathematics)

In mathematics, a group extension is a general means of describing a group in terms of a particular normal subgroup and quotient group. If Q and N are two groups, then G is an extension of Q by N if there is a short exact sequence

PAIR OF A MATHEMATICAL FIELD AND ITS SUBFIELD

Subfield (mathematics); Quadratic extension; Purely transcendental; Extension field; Quadratic field extension; Degree (field theory); Subextension (field theory); Trivial extension; Intermediate field; Adjunction (field theory); Extension of a field; Finitely generated field extension; Purely transcendental extension; Field Extension; Finitely generated extension; Subextension; Cubic field extension; Cubic extension; Transcendental field extension; Adjoining (field theory)

In mathematics, particularly in algebra, a field extension is a pair of fields E\subseteq F, such that the operations of E are those of F restricted to E. In this case, F is an extension field of E and E is a subfield of F.

Tracking ship

A tracking ship, also called a missile range instrumentation ship or range ship, is a ship equipped with antennas and electronics to support the launching and tracking of missiles and rockets. Since many missile ranges launch over ocean areas for safety reasons, range ships are used to extend the range of shore-based tracking facilities.

In the United States, the initial tracking ships were constructed by the U.S. Army and then the U.S. Air Force to support their missile programs. They were generally built on a surplus Liberty ship or Victory ship hull. By 1964, the U.S. Navy took over all the range ships and introduced more.

In some Navies, such a ship is also given the Type Designation "Vigilship" or "Veladora", with the Designation Letter "V" or Letters "VC".
