About Approximation Multinominals, Orthogonal on Any Grids
In this work are investigated approximation properties of multinominals pn(x), orthogonal with weight ∆tj - on the any grids consisting of final number of points of a piece [-1,1]. Namely the approximation formula, in which is established at increase n together with N, approximation behaviour of these multinominals close to approximation behaviour of multinominals Lasiandra.
