(n ) a variable, especially in a DO-loop, that appears only on the right side of an equals sign The variable is read only, it is never assigned a new value
Having a variance of zero An invariant assemblage can exist only at a unique point in pressure-temperature-composition space, and projects to a point in the P-T projection of a system A non-degenerate invariant point involves c+2 phases, where c in the number of components in the system (so 4 phases in a binary system)
an assertion that must be true both before and after the execution of each operation (e g , application use case, class method) See also postcondition and precondition
In topology, a number, polynomial, or other quantity associated to a topological object such as a knot or 3-manifold which depends only on the underlying object and not on its specific description or presentation
An invariable quantity; specifically, a function of the coefficients of one or more forms, which remains unaltered, when these undergo suitable linear transformations
persistent in occurrence and unvarying in nature; "maintained a constant temperature"; "a constant beat"; "principles of unvarying validity"; "a steady breeze"
An assertion that should be true of an object at all times (except maybe while the object is being modified)
An assertion that should always be true for a specified segment or at a specified point of a computer program From [IEEE90]
In mathematics, a fixed point (sometimes shortened to fixpoint, also known as an invariant point) of a function is a point that is mapped to itself by the function
(Elektrik, Elektronik) A time-invariant system (often refered to equivalently as a shift-invariant) is system for which a time shift or delay of the input sequence causes a corresponding shift in the output sequence
