Sandwich theorems for radiant functions
Abstract We show that between two graphs, one of a radiant function and the other of a coradiant, both defined…
On a property of moduli of smoothness and K-functionals
Abstract A new property of moduli of smoothness associated to functions belonging to some certain spaces is revealed. In terms…
Uniform approximation of some classes of linear positive operators expressed by series
Abstract The paper dealswith a general class of linear positive approximation processes designed using series. For continuous and bounded functions…
A sequence of positive linear operators associated with an approximation process
Abstract Considering a general class of discrete linear positive operators, by using a one-to-one function, we associate to the class…
Kantorovich sequences associated to general approximation processes
Abstract Starting from a general sequence of linear positive operators of discrete type we indicate a method to associate its…
A topological approach to the existence and multiplicity of positive solutions of (p,q)-Laplacian systems
AbstractIn this paper we develop a new theory for the existence, localization and multiplicity of positive solutions for a class…
Existence results for systems with nonlinear coupled nonlocal initial conditions
