Discrete Thermodynamics And Emergence Of Bifurcations In The Chemical   Systems
  The paper investigates emergence of pitchfork bifurcations in the chemical systems. The systems may be split conditionally by two groups, the strong and the weak, depending upon system complexity and its potential response to the external impact. This work investigates birth and development of bifurcations in the systems of both types. As a special case of a weak system with high degree of the equilibrium transformation, emergence of bifurcations was studied in the discrete thermodynamic model of 2-level laser.
