Abstract: The article considers an integral operator acting from Lebesque spaces to Lorentz spaces. The conditions are found under which the compact operator belongs to the Shatten–Neumann classes.

Key words: Lebesque spaces, Lorentz spaces, integral operator, approximation numbers, Shatten–Neumann norms.
