    On the non existence of periodic orbits for a class of two dimensional Kolmogorov systems by Rachid Boukoucha

    Published 2021-11-01
    “…In this paper we characterize the integrability and the non-existence of limit cycles of Kolmogorov systems of the form $$ x^{\prime}=x\left(B_{1}(x,y)\, \ln \left| \frac{A_{3}(x,y)}{A_{4}(x,y)}\right| + B_{3}(x,y)\ln \left| \frac{A_{1}(x,y)}{A_{2}(x,y)}\right| \right), $$ $$ y^{\prime}=y\left(B_{2}(x,y)\ln \left| \frac{A_{5}(x,y)}{A_{6}(x,y)}\right| + B_{3}(x,y)\ln \left| \frac{A_{1}(x,y)}{A_{2}(x,y)}\right| \right) $$ where $A_{1}\left( x,y\right) ,$ $A_{2}\left( x,y\right) ,$ $A_{3}\left( x,y\right) ,$ $A_{4}\left( x,y\right) ,$ $A_{5}\left( x,y\right) ,$ $A_{6}\left( x,y\right) ,$ $B_{1}\left( x,y\right) ,$ $B_{2}\left( x,y\right),$ $B_{3}\left( x,y\right) $ are homogeneous polynomials of degree $a,$ $a,$ $b,$ $b,$ $c,$ $c,$ $n,$ $n,$ $m$ respectively. …”
