| Abstract: | The Abel entropy group and its matrix representation with the general law of nonextensive entropy composition and quadratic
nonlinearity are defined. Four types of matrices for the corresponding parametrical entropies are given and geometries for
their measures are determined. New two-parameter entropy is introduced, and a distribution is found for equilibrium thermodynamics
of nonextensive systems.
