Etymology

Definitions

1. 1

   Having the quality of oneness.

   • If yes–no questions are CPs containing a null yes–no question operator (a null counterpart of whether) in spec-CP, we can arrive at a unitary characterisation of questions as CPs with an interrogative specifier.
2. 2

   That concentrates power in a single body, rather than sharing it with more local bodies.

   • a unitary authority
   • a unitary state
3. 3

   1. 4

      Whose inverse is equal to its adjoint.

      • The eigenvectors of an orthogonal or unitary operator, corresponding to different eigenvalues, are orthogonal.
      • In essence we are looking for some way to average the individual unitary matrices Uₖ. But a linear combination of unitary matrices does not remain unitary.
      • We then repeat the same procedure to the (d − 1) × (d − 1) block unitary matrix using (d − 2) two-level unitary matrices.
   2. 5

      A unitary council.

      • Outside the metropolitan areas most councils (English and Welsh counties, London boroughs, Scottish and Welsh unitaries, and Northern Ireland districts) are now elected en bloc every four years.
   3. 6

      A unitary matrix or operator.

      • Can unitaries in a unital C*-algebra with real rank zero be approximated by unitaries with finite spectrum?
