A characterization of generalized Lipschitz classes by the rate of convergence of semi-discrete operators
Danilo Costarelli, Michele Piconi, Gianluca Vinti
In this paper, we establish a comprehensive characterization of the generalized Lipschitz classes through the study of the rate of convergence of a family of semi-discrete sampling…
Advancements in nonlinear exponential sampling: convergence, quantitative analysis and Voronovskaya-type formula
Danilo Costarelli, Mariarosaria Natale
In this paper, we introduce the nonlinear exponential Kantorovich sampling series. We establish pointwise and uniform convergence properties and a nonlinear asymptotic formula of t…
A comparison among a fuzzy algorithm for image rescaling with other methods of digital image processing
Danilo Costarelli, Anna Rita Sambucini
The aim of this paper is to present a comparison among the fuzzy-type algorithm for image rescaling introduced by Jurio et al., 2011, quoted in the list of references, with some ot…
Max-product Kantorovich sampling operators: quantitative estimates in functional spaces
Lorenzo Boccali, Danilo Costarelli, Gianluca Vinti
In this paper, we study the order of approximation for max-product Kantorovich sampling operators based upon generalized kernels in the setting of Orlicz spaces. We establish a qua…
Convergence results in Orlicz spaces for sequences of max-product Kantorovich sampling operators
Lorenzo Boccali, Danilo Costarelli, Gianluca Vinti
In this paper, we provide a unifying theory concerning the convergence properties of the so-called max-product Kantorovich sampling operators based upon generalized kernels in the…
Quantitative estimates for nonlinear sampling Kantorovich operators
Nursel Cetin, Danilo Costarelli, Gianluca Vinti
In this paper, we establish quantitative estimates for nonlinear sampling Kantorovich operators in terms of the modulus of continuity in the setting of Orlicz spaces. This general…
