Abstract


The sequences of the translation invariant by the both arguments, continuous bilinear operators $$$T_n\colon L_1 \times L_1 \rightarrow L_0$$$ has been considered. The improvement of the smoothness of the functions belonging to the Lipschitz-Holder classes has been established.

Keywords


bilinear operators; translation invariant; smooth functions
