Streszczenie
Various new sufficient conditions for representation of a function of several variables as an absolutely convergent Fourier integral are obtained. The results are given in terms of $L_p$ integrability of the function and its partial derivatives, each with a different $p$. These $p$ are subject to certain relations known earlier only for some particular cases. Sharpness and applications of the results obtained are also discussed.
