S. S. Volosivets, A. N. Mingachev Saratov State University
Abstract:
The series of one-dimensional and two-dimensional Fourier coefficients with respect to multiplicative systems $\chi$ (with a bounded generating sequence ${\mathbf P}=\{p_i\}^\infty_{i=1}$) with weights satisfying Gogoladze–Meskhia type conditions are studied. Sufficient conditions for the convergence of such series are established for functions from different classes of generalized bounded fluctuation.
Keywords:
absolute convergence, multiplicative system, double series, generalized bounded fluctuation.
