Streszczenie
The weak type maximal principles of Stein and Sawyer are extended to nets of operators defined on classes of functions on general measure spaces (possibly of infinite measure), including the case of locally compact groups. Applications to differentiation of integrals, multiple Fourier series and multi-parameter ergodic averages are given.
