Rank of a Lie group
From Encyclopedia of Mathematics
(real or complex)
The (real, respectively, complex) dimension of any Cartan subgroup of it. The rank of a Lie group coincides with the rank of its Lie algebra (see Rank of a Lie algebra). If a Lie group 
coincides with the set of real or complex points of a linear algebraic group 
, then the rank of 
coincides with the rank of 
(cf. Rank of an algebraic group).
