On rational functions of the best nonsymmetric approximations in integral metrics
We obtain theorems that characterize the degree of the rational function of the best (α; β) -approximation in the space L p and conditions under which the value of the best rational (α; β) -approximation is less than the best (α; β) -approximation by algebraic polynomials.
