invariance
Resistance to change
Invariance is the quality of remaining unchanged under specified conditions or transformations.
The term appears most often in mathematics, physics, and computer science, where certain properties stay constant even as other variables shift: The invariance of physical laws under rotation is a fundamental principle.
Something exhibiting invariance is invariant.
