We discuss coexistence and extinction of one or both species, and describe the domain of attraction of nontrivial periodic solutions in the axes, under conditions that generalise Gopalsamy conditions. Finally, we apply our results to a model of microbial growth and to a model of phyto-plankton competition under the e_ect of toxins.engPeriodic Kolmogorov systemExtinctionCoexistenceExtinction or coexistence in periodic Kolmogorov systems of competitive typejournal article10.3934/dcds.20210941553-5231
