Deryabin, M. V. Polynomial integrals of dynamical systems and the Lax reduction. (English. Russian original) Zbl 0915.58039 Math. Notes 61, No. 3, 363-365 (1997); translation from Mat. Zametki 61, No. 3, 445-446 (1997). The author considers partial differential equations of so-called hydrodynamic type. It is proved the hydrodynamical integrability of such equations.
