invariant
31Invariant (computer science) — In computer science, a predicate that, if true, will remain true throughout a specific sequence of operations, is called (an) invariant to that sequence.UseAlthough computer programs are typically mainly specified in terms of what they change, it …
32Invariant speed — The invariant speed or observer invariant speed is the speed an object or particle must be traveling at for its speed to have the same measure in all reference frames. The invariance of the speed of light is a consequence of the postulates of… …
33Invariant de Lorentz — Invariance de Lorentz Dans le cadre de la relativité restreinte (qui reste valable aussi en relativité générale), une quantité est dite invariante de Lorentz, on dit aussi scalaire de Lorentz, ou invariant relativiste, lorsqu elle n est pas… …
34Invariant relativiste — Invariance de Lorentz Dans le cadre de la relativité restreinte (qui reste valable aussi en relativité générale), une quantité est dite invariante de Lorentz, on dit aussi scalaire de Lorentz, ou invariant relativiste, lorsqu elle n est pas… …
35Invariant basis number — In mathematics, the invariant basis number (IBN) property of a ring R is the property that all free modules over R are similarly well behaved as vector spaces, with respect to the uniqueness of their ranks. Definition A ring R has invariant basis …
36Invariant chain — The invariant chain is a special polypeptide involved in the formation and deliverance of MHC class II protein.The nascent MHC class II protein in the rough ER has its peptide binding cleft blocked by the invariant chain (Ii; a trimer) to prevent …
37Invariant de nœuds — Les deux nœuds sont les mêmes, leur invariant est donc identique. En théorie des nœuds, un invariant de nœuds est une quantité définie pour chaque nœud qui est la même pour tous les nœuds équivalents. On parlera d équivalence lorsqu on peut… …
38Invariant (physics) — In mathematics and theoretical physics, an invariant is a property of a system which remains unchanged under some transformation.The gravitational field of the Sun is invariant under a change of time (from, say, now to tomorrow). It is also… …
39Invariant polynomial — In mathematics, an invariant polynomial is a polynomial P that is invariant under a group Gamma acting on a vector space V. Therefore P is a Gamma invariant polynomial if :P(gamma x) = P(x) for all gamma in Gamma and x in V.Cases of particular… …
40Invariant factor — The invariant factors of a module over a principal ideal domain occur in one form of the structure theorem for finitely generated modules over a principal ideal domain.If R is a PID and M a finitely generated R module, then:Mcong R^roplus R/(a… …
