Nikolai Yu. Antonov Krasovskii Institute of Mathematics and Mechanics, Ural Branch of the Russian Academy of Sciences, Ekaterinburg
Аннотация:
We consider one type of convergence of multiple trigonometric Fourier series intermediate between the convergence over cubes and the $\lambda $-convergence for $\lambda >1$. The well-known result on the almost everywhere convergence over cubes of Fourier series of functions from the class $ L (\ln ^ + L) ^ d \ln ^ + \ln ^ + \ln ^ + L ([0,2 \pi)^d ) $ has been generalized to the case of the $ \Lambda $-convergence for some sequences $\Lambda$.
Ключевые слова:
Trigonometric Fourier series, Rectangular partial sums, Convergence almost everywhere.
