In this paper, our main aim is to obtain two different discrete chaotic dynamical systems on the Box fractal (B" role="presentation" style="font-size: 100%; display: inline-block; position: relative;">BB). For this goal, we first give two composition func... see more

In this paper we present some recent multiplicity results for a class of second order Hamiltonian systems. Exploiting the variational structure of the problem, it will be shown how the existence of multiple, even infinitely many, periodic solutions can be... see more

Numerous studies have been and are still being carried out on flows in periodic pattern channels. However, if these continue to multiply, it is because the phenomena involved are very complex and there are still a large number of poorly described points. ... see more

In this paper, the influence of additive Allee effect in prey and periodic harvesting in predator to the dynamics of the Leslie-Gower predator-prey model is proposed. We first simplify the model to the non-dimensional system by scaling the variable and tr... see more

I exemplify various elementary cases of fuzzy sequences and results related to the iteration of fuzzy mappings and to fuzzy logic systems (FLS). Several types of fuzzy logic system iterations are exemplified in relationship with oscillations in FLS and wi... see more

We consider the Bojanov-Naidenov problem over the set sh,r\sigma_{h,r} of all non-periodic splines ss of order rr and minimal defect with knots at the points khkh, k?Zk \in \mathbb{Z}. More exactly, for given n,r?Nn, r \in \mathbb{N}; p,A>0p, A > 0 and... see more

In the article, some non-regular F(p) field is determined (the non-regular function of the p=x+iy variables). We obtain a main result after consideration of the F(p) values: F(p)=f(p-2A), if p=x+iy, x=A, for all  A.  The F(A+iy) values are equal... see more

It is given a non trivial example of nonempty subset I of C0([0,1]2) such that: whatever F ? I be, for the pair ([0,1]2,F)  the successive approximations method converges globally (i.e. For each P ? [0,1]2 the sequence (Fn(P))n? N converges to a fi... see more
