  4. Dilation (operator theory) - Wikipedia

    en.wikipedia.org/wiki/Dilation_(operator_theory)

    In operator theory, a dilation of an operator T on a Hilbert space H is an operator on a larger Hilbert space K, whose restriction to H composed with the orthogonal projection onto H is T. More formally, let T be a bounded operator on some Hilbert space H, and H be a subspace of a larger Hilbert space H' . A bounded operator V on H' is a ...

  5. Hodge star operator - Wikipedia

    en.wikipedia.org/wiki/Hodge_star_operator

    The combination of the operator and the exterior derivative d generates the classical operators grad, curl, and div on vector fields in three-dimensional Euclidean space. This works out as follows: d takes a 0-form (a function) to a 1-form, a 1-form to a 2-form, and a 2-form to a 3-form (and takes a 3-form to zero).

    A rival restaurant owner, Flanagan, visits Dandy Donuts and taunts Cliff with his new, healthier pastry. Cliff then convinces Flanagan to take home a sugar donut, unaware that the donut is contaminated. Later, while Flanagan is in the shower, the donut mutates and eats him alive.

  7. Relational operator - Wikipedia

    In computer science, a relational operator is a programming language construct or operator that tests or defines some kind of relation between two entities. These include numerical equality ( e.g. , 5 = 5 ) and inequalities ( e.g. , 4 ≥ 3 ).

    FCC amateur radio station license of Al Gross. In the United States, amateur radio licensing is governed by the Federal Communications Commission (FCC). Licenses to operate amateur stations for personal use are granted to individuals of any age once they demonstrate an understanding of both pertinent FCC regulations and knowledge of radio station operation and safety considerations.

  9. C++ - Wikipedia

    en.wikipedia.org/wiki/C++

    C++ provides more than 35 operators, covering basic arithmetic, bit manipulation, indirection, comparisons, logical operations and others. Almost all operators can be overloaded for user-defined types, with a few notable exceptions such as member access (. and .*) and the conditional operator. The rich set of overloadable operators is central ...
