  Article:   ON TWO MODIFIED PHILLIPS OPERATORS.

Authors:  GANCHO TACHEV.
 
       
         
  Abstract:  
In this note we introduce two new modified Phillips operators G1n and
G2n. We obtain direct estimates for approximation of bounded continuous functions, defiined on [0;¥) by G1n, as well as for approximation of unbounded continuous functions by G2n. We improve some previous results on this topic.
Mathematics Subject Classification (2010): 41A25, 41A36.
Keywords: Phillips operators, exponential functions, quantitative results.
