Victoria Otero-Espinar, Claudia Valls, The zero-Hopf bifurcations in the Kolmogorov systems of degree 3 in R3, Communications in Nonlinear Science and Numerical Simulation, Volume 95, 2021, 105621, ISSN 1007-5704, https://doi.org/10.1016/j.cnsns.2020.105621.1007-5704https://hdl.handle.net/10347/39011In 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.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article10.1016/j.cnsns.2020.105621open access
