RT Journal Article T1 The zero-Hopf bifurcations in the Kolmogorov systems of degree 3 in R3 A1 Llibre, Jaume A1 Valls, Claudia A1 Diz Pita, Erika A1 Otero Espinar, María Victoria AB In this work we study the periodic orbits which bifurcate from all zero-Hopf bifurcations that an arbitrary Kolmogorov system of degree 3 in R 3 can exhibit. The main tool used is the averaging theory.
