摘要：

We use the methods developed in [Pierre-Emmanuel Caprace, "Abstract" homomorphisms of split Kac-Moody groups, Mem. Amer. Math. Soc. 198 (2009); Pierre-Emmanuel Caprace, Bernhard Muhlherr, Isomorphisms of Kac-Moody groups, Invent. Math. 161 (2005) 361-388; Pierre-Emmanuel Caprace, Bernhard Muhlherr, Isomorphisms of Kac-Moody groups which preserve bounded subgroups, Adv. Math. 206 (2006) 250-278] to solve the isomorphism problem of unitary forms of infinite split Kac-Moody groups over finite fields of square order. (C) 2009 Elsevier Inc. All rights reserved.
