a class invariant (or type invariant) is an invariant used for constraining objects of a class. Methods of the class should preserve the invariant. The...

In mathematics, an invariant is a property of a mathematical object (or a class of mathematical objects) which remains unchanged after operations or transformations...

then f {\displaystyle f} is said to be class invariant under ∼ , {\displaystyle \,\sim \,,} or simply invariant under ∼ . {\displaystyle \,\sim .} This...

Look up invariance, invariant, or invariants in Wiktionary, the free dictionary. Invariant and invariance may refer to: Invariant (computer science),...

In computer science, a loop invariant is a property of a program loop that is true before (and after) each iteration. It is a logical assertion, sometimes...

contracts are concepts of class invariant. The class invariant guarantees (for the local class) that the state of the class will be maintained within...

describe a particular language behavior. In RAII, holding a resource is a class invariant, and is tied to object lifetime. Resource allocation (or acquisition)...

of state is necessary for being able to enforce the invariants of the class. The behavior of a class or its instances is defined using methods. Methods...

(such as those that would be loaded onto class I MHC). The invariant chain also facilitates the export of class II MHC from the ER to the Golgi apparatus...

declaring class. They have the task of initializing the object's data members and of establishing the invariant of the class, failing if the invariant is invalid...

conditions in a given symplectic manifold. The GW invariants may be packaged as a homology or cohomology class in an appropriate space, or as the deformed cup...

morphism for ∼ , {\displaystyle \,\sim ,} a class invariant under ∼ , {\displaystyle \,\sim ,} or simply invariant under ∼ . {\displaystyle \,\sim .} This...

In the mathematical field of knot theory, a knot invariant is a quantity (in a broad sense) defined for each knot which is the same for equivalent knots...

Gromov–Witten invariants. Chern classes were introduced by Shiing-Shen Chern (1946). Chern classes are characteristic classes. They are topological invariants associated...

contract (DbC), in which assertions, preconditions, postconditions, and class invariants are employed to help ensure program correctness without sacrificing...

"invariant". More formally, a graph property is a class of graphs with the property that any two isomorphic graphs either both belong to the class, or...

contract. Design by contract also includes notions of postcondition and class invariant. The precondition for any routine defines any constraints on object...

In the field of mathematics known as functional analysis, the invariant subspace problem is a partially unresolved problem asking whether every bounded...

symmetric holomorphic function on the complex upper half-plane. It is invariant under the fractional linear action of the congruence group Γ(2), and generates...

In mathematics, Felix Klein's j-invariant or j function is a modular function of weight zero for the special linear group SL ⁡ ( 2 , Z ) {\displaystyle...

discussed below. A natural approach is to make holding a resource be a class invariant: resources are acquired during object creation (specifically initialization)...

the topological invariant of the topological insulators and topological superconductors, given a dimension and discrete symmetry class. The ten possible...

CLIP or Class II-associated invariant chain peptide is the part of the invariant chain (Ii) that binds to the peptide binding groove of MHC class II and...

In mathematics, the Arf invariant of a nonsingular quadratic form over a field of characteristic 2 was defined by Turkish mathematician Cahit Arf (1941)...

HLA class II histocompatibility antigen gamma chain also known as HLA-DR antigens-associated invariant chain or CD74 (Cluster of Differentiation 74), is...

geometric topology, the mapping class group is an important algebraic invariant of a topological space. Briefly, the mapping class group is a certain discrete...

In number theory, the class number formula relates many important invariants of an algebraic number field to a special value of its Dedekind zeta function...

invariant of an algebra is an invariant attached to a Brauer class of algebras over a field. The concept is named after Helmut Hasse. The invariant plays...
