Abstract
We introduce a new class of double sequences called $\mathit {DGM}(\alpha ,\beta ,\gamma ,r)$, which is a generalization of the class considered by Kórus. Moreover, we obtain sufficient and necessary conditions for uniform convergence of double sine series with coefficients from this class.
