Properties of Cesàro Means of Double Fourier Series / D'yachenko A.M. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2010. ? 2. P. 3-11 [Moscow Univ. Math. Bulletin. Vol. 65, No 2, 2010. P. 55-62]. The pointwise behavior of partial sums and Cesàro means of trigonometric series were studied in many papers. This paper deals with the behavior of rectangular Cesàro means at a point (x0,y0) for functions f(x,y) bounded in the square [-π; π]2 and satisfying the condition
Key words: Chesàro means, Fourier series.
