Generalized special orthogonal group
In
mathematics, a
generalized special orthogonal group, SO(p,q) is the
group of all linear transformations of a p+q dimensional
real vector space (for
complex vector spaces, there is no difference between SO(p,q) and SO(p+q)) which leave invariant a symmetric 2-
tensor with p positive and q negative eigenvalues.
