On the Bézout equation in the ring of periodic distributions
Rudolf Rupp, Amol Sasane (2016)
Topological Algebra and its Applications
A corona type theorem is given for the ring D'A(Rd) of periodic distributions in Rd in terms of the sequence of Fourier coefficients of these distributions,which have at most polynomial growth. It is also shown that the Bass stable rank and the topological stable rank of D'A(Rd) are both equal to 1.
On the degree of convergence of Borel and Euler means for double Fourier series of functions of bounded variation in Hardy sense
Maria Topolewska (1995)
Mathematica Bohemica
For real functions of bounded variation in the Hardy sense, -periodic in each variable, the rates of pointwise convergence of the Borel and Euler means of their Fourier series are estimated.

On the Mixed Modulus of Smoothness and a Class of Double Fourier Series
Krasniqi, Xhevat Z. (2013)
Mathematica Balkanica New Series
MSC 2010: 42A32; 42A20In this paper we have defined a new class of double numerical sequences. If the coefficients of a double cosine or sine trigonometric series belong to the such classes, then it is verified that they are Fourier series or equivalently their sums are integrable functions. In addition, we obtain an estimate for the mixed modulus of smoothness of a double sine Fourier series whose coefficients belong to the new class of sequences mention above.
