On Szasz-Mirakyan Operators Preserving e(2ax), a > 0
Acar, Tuncer; Aral, Ali; Gonska, Heiner (Springer Basel Ag, 2017)A modification of Szasz-Mirakyan operators is presented that reproduces the functions 1 and e(2ax), a > 0 fixed. We prove uniform convergence, order of approximation via a certain weighted modulus of continuity, and a ... -
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 ...
