The uniform convergence in question is defined by means of a system of mutually homotetic starlike polygons. It is established, among other things, that an arbitrary positive sequence in $l^2(\mathbb{T}^2)$ can be majorized by the sequence of absolute values of coefficients of a uniformly convergent double Fourier series.
