  • Minimax sums of posets and the quadratic Tits form 
    Bondarenko, V.M.; Polishchuk, A.M. (Algebra and Discrete Mathematics, 2004)
    In this paper we study the structure of infinite posets with positive Tits form. In particular, there arise posets of specific form which we call minimax sums of posets.
