| contents | We present mixing ergodic automorphisms of a space with sigma-finite measure whose symmetric tensor squares have simple spectra. This property is of interest in connection with dynamical spectral problems of A.N. Kolmogorov and V.A. Rokhlin. Explicit examples are given in the class of near-Sidon constructions. |
