This paper is devoted to the construction of minimal rational bases of GL(2, R)-comitants and minimal rational bases of GL(2, R)-invariants for the bidimensional system of differential equations with nonlinearities of the fourth degree. For this system, three minimal rational bases of GL(2,R)-comitants and two minimal rational bases of GL(2, R)-invariants were constructed. It was established that any minimal rational basis of GL(2, R)-comitants contains 13 comitants and each minimal rational basis of GL(2, R)-invariants contains 11 invariants. |
