The Haar measures are used in harmonic analysis on locally compact groups, particularly in the theory of Pontryagin duality. To prove the existence of a Haar measure on a locally compact group it suffices to exhibit a left-invariant Radon measure on . Mathematical statistics See more In mathematical analysis, the Haar measure assigns an "invariant volume" to subsets of locally compact topological groups, consequently defining an integral for functions on those groups. This See more There is, up to a positive multiplicative constant, a unique countably additive, nontrivial measure $${\displaystyle \mu }$$ on the Borel … See more A construction using compact subsets The following method of constructing Haar measure is essentially the method used by Haar and Weil. For any subsets See more In the same issue of Annals of Mathematics and immediately after Haar's paper, the Haar theorem was used to solve Hilbert's fifth problem restricted to compact groups by John von Neumann. Unless $${\displaystyle G}$$ is a discrete group, it is … See more Let $${\displaystyle (G,\cdot )}$$ be a locally compact Hausdorff topological group. The $${\displaystyle \sigma }$$-algebra generated by all open subsets of $${\displaystyle G}$$ is called the Borel algebra. An element of the Borel algebra is called a See more • If $${\displaystyle G}$$ is a discrete group, then the compact subsets coincide with the finite subsets, and a (left and right invariant) Haar measure on $${\displaystyle G}$$ is the counting measure. • The Haar measure on the topological group See more It can also be proved that there exists a unique (up to multiplication by a positive constant) right-translation-invariant Borel measure See more The no-hair theorem states that all stationary black hole solutions of the Einstein–Maxwell equations of gravitation and electromagnetism in general relativity can be completely characterized by only three independent externally observable classical parameters: mass, electric charge, and angular momentum. Other characteristics (such as geometry and magnetic moment) are uniquely determined by these three parameters, and all other information (for which "hair" is a metaphor…
