On a positive linear operator on the semiaxis

2010
A positive linear operator is introduced on the semiaxis and its convergence is investigated in suitable weighted spaces equipped with the uniform and the L1-norm. As corollaries, error estimates for a special Hermite-Fejer polynomial are obtained.
