Antimonotonous quadratic forms and partially ordered sets
L. A. Nazarova, A. V. Roiter, M. N. Smirnova
Antimonotonous quadratic forms generalizing P-faithful posets defined by authors earlier are introduced. The criterion of antimonotonousness is given for posets with positive semid…

Singular locally-scalar representations of quivers in Hilbert spaces and separating functions
I. K. Redchuk, A. V. Roiter
A numeric function : was considered in [1]. In its terms criterions of finite representability and tameness of marked quivers, posets with equi…

L. A. Nazarova, A. V. Roiter
Numerical functions, which characterize Dynkin schemes, Coxeter graphs and tame marked quivers, are considered.
