The Exact Form of the Second Moment of Third Degree Schoenberg Spline Operators. (17th August 2020) - Moldovan, Camelia Liliana
Abstract: The article presents an explicit form for the second moment of cubic Schoenberg operators with arbitrary knots and in the particular case of equidistant knots. Applications are given for quantitative direct results in approximation and in construction of special classes of Schoenberg operators.
