Quantitative Voronovskaya Type Theorems For A General Sequence of Linear Positive Operators
Aral, Ali; Tachev, Gancho (Univ Nis, Fac Sci Math, 2019)The present paper deal with the obtaining quantitative form of the results presented Butzer & Karsli [1]. That is, we prove quantitative simultaneous results by general sequence of positive linear operators which are valid ... -
Quantitative Voronovskaya-Type Results for Polynomially Bounded Functions
Aral, Ali; Gonska, Heiner; Heilmann, Margareta; Tachev, Gancho (Springer Basel Ag, 2016)We prove quantitative Voronovskaya-type results and Gruss-Voronovskaya inequalities for polynomially bounded functions. The results are given in terms of suitable K-functionals and applied to linking Szasz-Mirakyan and ... -
Voronovskaja's theorem for functions with exponential growth
Tachev, Gancho; Gupta, Vijay; Aral, Ali (WALTER DE GRUYTER GMBH, 2020)In the present paper we establish a general form of Voronovskaja's theorem for functions defined on an unbounded interval and having exponential growth. The case of approximation by linear combinations is also considered. ...
