In this work, we model the relationship between prey and predators by studying the
interactive behavior of this prey‐predator model and using the change of prey. The objective …

In the past few years, the parapenaeus longirostris population stock has seen a sharp
reduction. In this work, we propose a bioeconomic model that represents the biomass …

We expose our work on interpolative Kannan and CRR-type contractions on non complete
metric spaces. Some results were found by previous authors in the case where the space is …

The linear complementarity problem is receiving a lot of attention and has been studied
extensively. Recently, El foutayeni et al. have contributed many works that aim to solve this …

In this work, we describe the predation interaction between phytoplankton and zooplankton
(Crustacean) organisms under their exploitation by a bioeconomic spatiotemporal discrete …

The aim of this work is to study the optimal control strategy of a mathematical model of the
COVID-19 transmission in the discrete case, and to investigate, in discrete time, optimal …

In this work, we propose a biological model for a migratory mammal species Balaenoptera
physalus and the two small pelagic species Sardina pilchardus and Engraulidae. Phocoena …

The management of plankton production constitutes a major challenge for the development
of aquaculture. To attend this objective, chlorophyll-a, a pigment present in all …

L'impact de la pandémie de coronavirus (Covid-19) sur l'économie mondiale pourrait être
compris entre 2000 et 4100 milliards de dollars, soit 2, 3% à 4, 8% du PIB mondial. Le choc …

Dans les domaines de la recherche opérationnelle et de l'optimisation, les problèmes de
complémentarité linéaire sont largement reconnus, mais ces problèmes sont souvent …
