For the first time, the connection of the nonlinear deformed algebra with the linear one is found. Conditions to realize the optimal evolution of spin systems are established. For the first time, a microscopic black hole is consudered in the case of a generalized uncertainty relation with minimal length and momentum. The full density matrix of the system "Bose-liquid + impurity atom" is obtained in the approximation of pair correlations. For the first time, the existence of a phase transition is predicted in a system obeying the Polychronakos statistics with a complex parameter and estimations about its experimental observations are made. Two-parametric fractional statistics are applied to model weakly-interacting and finite Bose-systems as well as the ideal anyon gas.
