Abstract

The convergence of Cesàro means of negative order of double trigonometric Fourier series of functions of bounded partial λ-variation is investigated. The sufficient and neccessary conditions on the sequence λ = {λ _n} are found for the convergence of Cesaro means of Fourier series of functions of bounded partial λ-variation.
