    Abstract:

In this paper we study approximation properties for the class of general integral operators of the form

$displaystyle (T_wf)(s) = int_{H_w} K_w (s,t, f(t)) dmu_{H_w}(t)    sin G, w>0$    

where $ G$ is a locally compact Hausdorff topological space, $ (H_w)_{w>0}$ is a net of closed subsets of $ G$ with suitable properties and, for every $ w>0,$ $ mu_{H_w}$ is a regular measure on $ H_w.$ We give pointwise, uniform and modular convergence theorems in abstract modular spaces and we apply the results to some kinds of discrete operators including the sampling type series.
