The Arrows block (U+2190–U+21FF) contains line, curve, and semicircle arrows and arrow-like operators. The math subset of this block is U+2190–U+21A7, U+21A9–U+21AE, U+21B0–U+21B1, U+21B6–U+21B7, U+21BC–U+21DB, U+21DD, U+21E4–U+21E5, U+21F4–U+21FF.
Old-fashioned doughnuts – cinnamon sugar (left), chocolate glazed (centre top) and maple glazed (right). Shape shown is typical of commercially available buttermilk donuts. The old-fashioned doughnut is a term used for a variety of cake doughnut prepared in the shape of a ring with a cracked surface and tapered edges around it. [1]
d'Alembert operator. In special relativity, electromagnetism and wave theory, the d'Alembert operator (denoted by a box: ), also called the d'Alembertian, wave operator, box operator or sometimes quabla operator [1] ( cf. nabla symbol) is the Laplace operator of Minkowski space. The operator is named after French mathematician and physicist ...
APL is going to execute from right-to-left. Step 1 {of topmost APL code entered at left}) 4-5 = -1. Step 2) 3 times -1 = -3. Step 3) Take the floor or lower of 2 and -3 = -3. Step 4) Divide 1 by -3 = -0.3333333333 = final result. An operator may have function or data operands and evaluate to a dyadic or monadic function.
ACP-131 [1] is the controlling publication for the listing of Q codes and Z codes. It is published and revised from time to time by the Combined Communications Electronics Board (CCEB) countries: Australia, New Zealand, Canada, United Kingdom, and United States. When the meanings of the codes contained in ACP-131 are translated into various ...
Since the stabilizer operators of the toric code are quasilocal, acting only on spins located near each other on a two-dimensional lattice, it is not unrealistic to define the following Hamiltonian, H T C = − J ∑ v A v − J ∑ p B p , J > 0. {\displaystyle H_{\rm {TC}}=-J\sum _{v}A_{v}-J\sum _{p}B_{p},\,\,\,J>0.}

Superoperator. In physics, a superoperator is a linear operator acting on a vector space of linear operators. [1] Sometimes the term refers more specially to a completely positive map which also preserves or does not increase the trace of its argument. This specialized meaning is used extensively in the field of quantum computing, especially ...
Scope resolution operator. In computer programming, scope is an enclosing context where values and expressions are associated. The scope resolution operator helps to identify and specify the context to which an identifier refers, particularly by specifying a namespace or class.
In quantum mechanics, for systems where the total number of particles may not be preserved, the number operator is the observable that counts the number of particles. The following is in bra–ket notation: The number operator acts on Fock space. Let. be a Fock state, composed of single-particle states drawn from a basis of the underlying ...
