文摘Abstract. This paper proves the sandwich classification conjecture for subgroups of an even dimensional hyperbolic unitary group U2n(R, A) which are normalized by the elementary subgroup EU2n(R, A), under the condition that R is a quasi-finite ring with involution, i.e., a direct limit of module finite rings with involution, and n ≥ 3. 2010 Mathematics Subject Classification: 20G35, 20H25
