AB - We establish a general sufficient condition for the possibility of representation of functions$$f\left( \max \left\{\left|{x}_1\right|,\left|{x}_2\right|\right\}\right)$$in the form of absolutely convergent double Fourier integrals and study the possibility of its application to various problems of summability of double Fourier series, in particular, by using the Marcinkiewiczâ€“Riesz method.
