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]
In Clifford analysis, the operator D : C ∞ (R k ⊗ R n, S) → C ∞ (R k ⊗ R n, C k ⊗ S) acting on spinor valued functions defined by f ( x 1 , … , x k ) ↦ ( ∂ x 1 _ f ∂ x 2 _ f … ∂ x k _ f ) {\displaystyle f(x_{1},\ldots ,x_{k})\mapsto {\begin{pmatrix}\partial _{\underline {x_{1}}}f\\\partial _{\underline {x_{2}}}f\\\ldots ...
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.
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.
A doughnut, or donut, is a thin metal or cardboard panel, similar in shape and appearance to a colour frame, but with a small diameter hole intended to reduce off-axis rays of light being projected from a fixture. This increases sharpness of the light by reducing the effect of imperfect lenses.
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 ...
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.}
Using this definition, we can write the multimode displacement operator as D ^ ψ ( α ) = exp ( α A ^ ψ † − α ∗ A ^ ψ ) {\displaystyle {\hat {D}}_{\psi }(\alpha )=\exp \left(\alpha {\hat {A}}_{\psi }^{\dagger }-\alpha ^{\ast }{\hat {A}}_{\psi }\right)} ,
In quantum mechanics, the exchange operator , also known as permutation operator, is a quantum mechanical operator that acts on states in Fock space. The exchange operator acts by switching the labels on any two identical particles described by the joint position quantum state . [1]
