Abstract: A group G is called T-Jordan if there is a constant J(G) such that every torsion subgroup of G contains a abelian subgroup of index J. In a 1976 paper, Dong Hoon Lee showed that a connected Lie group is T-Jordan. Similarly to the question of when automorphism groups of varieties are Jordan, one can consider the question when they are T-Jordan. Following Jia Jia's paper we will discuss the T-Jordan property in the case of compact complex surfaces.
