In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
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.
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.}
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.
The five-qubit error correcting code is the smallest quantum error correcting code that can protect a logical qubit from any arbitrary single qubit error. In this code, 5 physical qubits are used to encode the logical qubit. [2]
United States. I2. IBS. Iberia Express. IBEREXPRESS. Spain. Charter service, low cost carrier for EU flights of Iberia operating only A320s. IBR. Ibertour Servicios Aéreos.
This is a list of all airline codes. The table lists the IATA airline designators , the ICAO airline designators and the airline call signs (telephony designator). Historical assignments are also included for completeness.
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.
Porting Authorization Code (PAC) is a unique identifier (normally 9 characters long and in the format "ABC123456") used by some mobile network operators to facilitate mobile number portability (MNP). This allows users to retain their mobile telephone number when switching operators.
