We consider a homogeneous degenerate center of order 2m + 1 and perturb it by a homogeneous polynomial of order 2m. We study the Lyapunov constants around the origin to estimate the number of limit cycles. To do it, we classify the parameters and stu

We develop methods giving sufficient conditions for the existence of bounded solutions near homoclinic orbits of planar R.D.E.s. We provide families of bounded solutions near the homoclinic by decomposing the corresponding variational equation of the

We consider a predator–prey model of Leslie type with ratio-dependent simplified Holling type-IV functional response. The novelty of the model is that the functional response simulates group defense of the prey kind, which in turn, affects permanen

We seek a sufficient condition which preserves almost-invariant subspaces under the weak limit of bounded operators. We study the bounded linear operators which have a collection of almost-invariant subspaces and prove that a bounded linear operator

This paper proposes a planar delay differential equation for cancer virotherapy. The model simulates the situation in which an oncolytic virus is injected for the second time, and the immune system suppresses the viral infection with a time delay. Ou

One of the most significant issues investigated in reverse engineering (RE) is the problem of finding the best surface that approximates point cloud data. In recent years, some studies have been carried out for the segmentation of industrial mesh mod

We consider a planar delay differential equation which is motivated biologically and simulates a cancer virotherapy. The singularities and their local stability are studied using the characteristic equation. Because of biological importance, we inves
