In abstract algebra, the Cartan–Brauer–Hua theorem (named after Richard Brauer, Élie Cartan, and Hua Luogeng) is a theorem pertaining to division rings.
 It says that given two division rings "K" ⊆ "D" such that "xKx" is contained in "K" for every "x" not equal to 0 in "D", either "K" is contained in the center of "D", or "K" = "D" .
 In other words, if the unit group of "K" is a normal subgroup of the unit group of "D", then either "K" = "D" or "K" is central .
