The subgroup of a semi-simple algebraic group , defined over a field , which is the commutator subgroup of the centralizer of a maximal -split torus ; . The anisotropic kernel is a semi-simple anisotropic group defined over ; . The concept of the anisotropic kernel plays an important role in the study of the -structure of [1]. If , i.e. if , then is anisotropic over ; if , the group is called quasi-split over .
