| Résumé: | The objective of this thesis is the qualitative study of some classes of Kolmogorov differential systems.In the first chapter,we introduced some of the basic concepts needed for the qualitative study of dynamics systems.In the second chapter,we presented our first result on the construction of a class of differential systems of Kolmogorov type,with algebraic limit cycles and we give the explicit expression of these limit cycles.In chapter three,we presented our second result on the integrability of a class of Kolmogorov type differential systems of degree seven with a non-algebraic limit cycle and we give its explicit expression.At the end of each chapter,examples of illustrations are given. |
