Goldie’s theorem


Let R be a ring with an identityPlanetmathPlanetmath. Then R has a right classical ring of quotients Q which is semisimplePlanetmathPlanetmathPlanetmathPlanetmath ArtinianPlanetmathPlanetmath if and only if R is a semiprime right Goldie ring. If this is the case, then the compositionMathworldPlanetmathPlanetmath length of Q is equal to the uniform dimension of R.

An immediate corollary of this is that a semiprime right Noetherian ring always has a right classical ring of quotients.

This result was discovered by Alfred in the late 1950’s.
