The sentence "It is invariant" is correct and usable in written English.
You can use it when describing a situation or thing that is unchangeable or consistent, like a mathematical equation or a physical law. For example: "The speed of light is an invariant, meaning it remains the same regardless of the observer's frame of reference."
Because the target T-C istandingng, this shadow zone is the static one, i.e. it is invariant regarding its shape, location and additional attenuation.
Then, a module M having an ({mathcal {X}} -envelope (resp., ({X}} -envelope-coveresp. called ({mathcal {X}} -coverorphism invariant (resp., ({X}} -cover}})-automorphism calledriant) when it is invariant under any automorphism of its ({mathcal {X}} -automorphismsp., ({X}} -automorphismer).
And M is called ({mathcal {X}} -endomorphism invariant (resp., ({X}} -endomorphismomorphinvariantaresp.) when it is invariant under any endomorphism of its ({mathcal {X}} -endomorphismsp., ({X}} -endomorphismer) (see [11]).
Bearing in mind that a module M is quasi-injective if and only if it is invariant under any endomorphism of its injective envelope, the above arguments can be easily adapted to prove: Let R be a commutative noetherian ring and M, an R-module.
Definition 4 A function f : X n → Y will be called symmetric if it is invariant under a permutation of its arguments; that is, f ( x 1 ′, …, x n ′ ) = f ( x 1, …, x n ). for all x 1, …, x n ∈ X and ( x 1 ′, …, x n ′ ) denotes any permutation of ( x 1, …, x n ).
Therefore, such a slope is analogous to the TNR although, unlike that ratio, it is invariant.
Furthermore, it is invariant with respect to scale, and supports symbol recognition independently from the number and order of strokes.
The gap does not originate from the conventional Bragg scattering mechanism in that it is invariant with the change of scale length.
The vector compresses 3D object data from assembly parts and it is invariant to scale, rotation and orientation, and it also supports a wide range of illumination levels.
Rb shows a linear variation with valinomycin/K+ ratio between 0 and 1, but it is invariant at higher valinomycin/K+ ratios.
It is shown that real rank zero is equivalent to the previously defined conditions FS and HP, and that it is invariant under strong Morita equivalence, in particular under stable isomorphism.
