摘要：

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