    en.wikipedia.org/wiki/Choi's_theorem_on...

    The vector space C nm can be viewed as the direct sum = compatibly with the above identification and the standard basis of C n. If P kC m × nm is projection onto the k-th copy of C m, then P k * ∈ C nm×m is the inclusion of C m as the k-th summand of the direct sum and

  3. Stinespring dilation theorem - Wikipedia

    en.wikipedia.org/wiki/Stinespring_dilation_theorem

    The triple (π, V, K) is called a Stinespring representation of Φ. A natural question is now whether one can reduce a given Stinespring representation in some sense. Let K 1 be the closed linear span of π (A) VH. By property of *-representations in general, K 1 is an invariant subspace of π (a) for all a. Also, K 1 contains VH. Define

  4. Binomial coefficient - Wikipedia

    en.wikipedia.org/wiki/Binomial_coefficient

    Alternative notations include C(n, k), n C k, n C k, C k n, [3] C n k, and C n,k, in all of which the C stands for combinations or choices; the C notation means the number of ways to choose k out of n objects. Many calculators use variants of the C notation because they can represent it on a single-line display.

    en.wikipedia.org/wiki/Differential_form

    In general, a k-form is an object that may be integrated over a k-dimensional manifold, and is homogeneous of degree k in the coordinate differentials ,, …. On an n-dimensional manifold, a top-dimensional form (n-form) is called a volume form. The differential forms form an alternating algebra.

    en.wikipedia.org/wiki/Local_government_in_New_Mexico

    In addition to municipalities, limited local authority can be vested in landowners' associations and districts. An example of the former is the Madrid Landowners' Association, which is the closest thing to local government in Madrid, New Mexico. Its authority comes from the restrictive covenants that are written into all deeds.

    Let now (), where < <, i.e. has codegree m-k, and let us suppose that whenever a closed form has codegree less than m-k, the form is exact. The form ω {\displaystyle \omega } can be decomposed as ω = d x m ∧ ω 0 + ω 1 {\displaystyle \omega =dx^{m}\wedge \omega _{0}+\omega _{1}} where neither ω 0 {\displaystyle \omega _{0}} nor ω 1 ...
