Dataset of phase portraits of the fractional prey-predator model with Holling type-II interaction (without predator harvesting)
Dane Badawcze
open access
The need for a fractional generalization of a given classical model is often due to new behaviors which cannot be taken into account by the model. In this situation, it can be useful to look for a fractional deformation of the initial system, trying to fit the fractional exponent of differentiation in order to catch properly the data.
