Intertwining approximation in space L p ,(I)‎, 0

الملخص EN

In this paper, we find the degree of best approximation between a pair of a nearly intertwining polynomials, and a pair of a nearly intertwining splines to a non-negative function ( ) ( ) in p L , "  , 0  p 1", we find the order of best a nearly intertwining approximation in the above terms.
