S.V. Astashkin, R.F. Uzbekov ON K-CLOSED SUBCOUPLES AND RELATIVE COMPLETIONS Let (X0,X1) be a Banach couple such that X1 in X0. Subcouples of the form (X0,Y1) with a subspace Y1 of codimension 1 of the space X1 are considered. M.M. Semenova DECOMPOSITION OF MULTIRATE MODELS OF CONTROLLABLE SYSTEMS A method of integral manifold is applied to study of multitempo nonlinear systems. The use of this method permits us to solve a problem of decomposition of multirate controllable systems. Local controllability of these systems is investigated. The application of the method is illustrated on example. T.A. Sribnaya THE CAFIERO CRITERION ON AN ORTHOMODULAR POSET The uniform exhaustivity Cafiero criterion is proved in the case of functions defined on an orthomodular poset and taking values in an arbitrary topological space (without considering any algebraic operation on it). Ch.A. Chikhanov ON THE FUCHS CLASS THIRD ORDER EQUATION In this paper 54 solutions of Fuchs class third order equation with three correct singular points are given. |
