Quantitative Korovkin theorems for sublinear, monotone and strongly translatable operators in $L^{p} ([0, 1]), 1 \leq p \leq + \infty$

Sorin G. Gal, Constantin P. Niculescu

By extending the classical quantitative approximation results for positive and linear operators in $L^{p} ([0, 1]), 1 \leq p \leq + \infty$ of Berens and DeVore in 1978 and of Swetits a…

Nonlinear versions of Korovkin's abstract theorems

Sorin G. Gal, Constantin P. Niculescu

In this paper we prove Korovkin type theorems for sequences of sublinear, monotone and weak additive operators acting on function spaces C(X); where X is a compact or a locally com…

Choquet operators associated to vector capacities

Sorin G. Gal, Constantin P. Niculescu

The integral representation of Choquet operators defined on a space C(X) is established by using the Choquet-Bochner integral of a real-valued function with respect to a vector cap…
