Numer Algor https://doi.org/10.1007/s11075-018-0538-7 ORIGINAL PAPER Modified Kantorovich operators with better approximation properties Vijay Gupta 1 · Gancho Tachev 2 · Ana-Maria Acu 3 Received: 27 September 2017 / Accepted: 30 April 2018 © Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract In the present paper, we study a new kind of Bernstein-Kantorovich- type operators. Here, we discuss a uniform convergence estimate for this modified form. Also, some direct estimates, which involve the asymptotic-type results, are established. Some numerical examples which show the relevance of the results are considered.
