In mathematics and physics, covariance is a measure of how much two variables change together, and may refer to:

Statistics[edit]

Geometry[edit]

Computer science[edit]

Physics[edit]

  • General covariance or simply covariance (inaccurate but common usage in quantum mechanics), the invariance of the mathematical form of physical laws under arbitrary differential coordinate transformations (including Lorentz transformations), strictly meaning invariance
  • Covariant transformation, a rule that describes how certain physical entities change under a change of coordinate system
  • Lorentz covariance, a property of space-time that follows from the special theory of relativity
  • Eddy covariance, an atmospheric flux measurement technique
