In this note we give some direct and inverse approximation theorems for the Picard singular integral in the exponential weighted spaces and some generalized Hölder spaces.
We obtain modular convergence theorems in modular spaces for nets of operators of the form , w > 0, s ∈ G, where G and H are topological groups and is a family of homeomorphisms Such operators contain, in particular, a nonlinear version of the generalized sampling operators, which have many applications in the theory of signal processing.
