Generalized conjugate partial sums of Fourier series are used to find jumps of functions. The rate of convergence is studied and sharp results are obtained.

We prove that if as max(|j|,|k|) → ∞, and , then f(x,y)ϕ(x)ψ(y) ∈ L¹(T²) and as min(m,n) → ∞, where f(x,y) is the limiting function of the rectangular partial sums , (ϕ,θ) and (ψ,ϑ) are pairs of type I. A generalization of this result concerning L¹-convergence is also established. Extensions of these results to double series of orthogonal functions are also considered. These results can be extended to n-dimensional case. The aforementioned results generalize work of Balashov [1],...
