QED processes at electron-positron colliders are considerd. We presentdifferential cross-sections for large-angle Bhabha scattering, annihilationinto muons and photons. Radiative corrections in the first order are taken intoaccount exactly. Leading logarithmic contributions are calculated in all ordersby means of the structure-function method. An accuracy of the calculation canbe estimated about 0.2%.Comment: 24 pages, LaTeX, 2 PS figures, numerical results for large-angle Bhabha are adde
