Abstract.
Problems of approximation nature are considered for some spaces of real and complex valued functions and also measures defined on a locally compact abelian group. The approximating subspaces are analogs of the spatial entire functions of exponential type. The problem of convergence of a sequence of Fejér type positive operators is studied.
Keywords.: Locally compact abelian group; space; measures space; character; Fourier transform; entire functions of exponential type; positive operators; Fejér operator
