COMPUTATION OF POLYNOMIALS, THE LEAST DEVIATING FROM ZERO IN L1 METRICS BY SOLVING EXTREMAL PROBLEMS
Autor:
Suleykin, A., Mammahajiyev, R.
In this paper, we consider polynomials that deviate least from zero in the L1 metric. Then we explicitly calculate Chebyshev polynomials of the second kind by solving extremal problems.

In Chaps. 5 and 6, we have focused on the study of problems where the analytical models involve the use of a single queue. The interest is now in considering problems where queues exchange traffic as in a network. We can have both open networks of qu

UDC 517.5 We develop a new approach to the proof of a generalized Jackson theorem providing an estimate for the best approximation by trigonometric polynomials with the help of the moduli of continuity of an arbitrary order. The proposed approach is

We consider the generalized Jackson theorem concerning estimates for the best approximation by trigonometric polynomials via the moduli of continuity of an arbitrary order. We improve the known estimates for moduli of continuity of the 4th and 6th or

Very simple methods for deriving upper estimates of the type of the generalized Jackson theorem for the best approximations of periodic functions are proposed, The results obtained are similar to the generalized Jackson theorem, providing estimates i

We analyze the degree of shape preserving weighted polynomial approximation for exponential weights on the whole real line. In particular, we establish a Jackson type estimate.
