  • Given an algebraic group G over a field k and a k-algebra R, the role of maximal abelian k-diagonalizable subalgebras (MAD for short) of G(R) is the same as that the split maximal torus play in G(k). Let G be a reductive group such that the derived subgroup is simply connected and let Spec(R) be a connected reduced affine scheme. This dissertation is to studying conjugacy problems related to MADs in G(R). First, we provide the conjugacy theorem for regular MADs. For arbitrary MADs, the conjugacy theorem does not exist. But we give the structure of MADs in the classical groups of type A;B;C and D.
