About Approximation Multinominals, Orthogonal on Any Grids
In this work are investigated approximation properties of multinominals <i>p</i><sub><i>n</i></sub><i>(x), </i>orthogonal with weight ∆t<sub>j </sub>- 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 <i>n </i>together with <i>N, </i>approximation behaviour of these multinominals close to approximation behaviour of multinominals Lasiandra.
