Is a conservative reversible dynamical system realisable as a non-holonomic one?

Ya. V. Tatarinov

Consider a system with two groupes of variables: the time derivatives of ’’coordinates” are linear and homogeneous on the ’’velocities”, the time derivatives of "velocities” are quadratic, and an integral also quadratic on the ”velocities” exists. The article establish generic conditions respecting which such dynamical equations represent a conservative nonholonomic system.
