Analysis of solutions for the fractional differential equation with Hadamard-type

open access: yesOpen Mathematics, 2023
We mainly consider the existence and stability results of the positive solutions for the fractional differential equation with Hadamard-type by applying fixed point theorems, if the nonlinearity may be continuous or singular.

Nash-type equilibria and periodic solutions to nonvariational systems

open access: yesAdvances in Nonlinear Analysis, 2014
The paper deals with variational properties of fixed points for contraction-type operators. Under suitable conditions, the unique fixed point of a vector-valued operator is a Nash-type equilibrium of the corresponding energy functionals. This is achieved

On the finite approximate controllability for Hilfer fractional evolution systems with nonlocal conditions

open access: yesOpen Mathematics, 2020
The aim of this study is to investigate the finite approximate controllability of certain Hilfer fractional evolution systems with nonlocal conditions. To achieve this, we first transform the mild solution of the Hilfer fractional evolution system into a

Localization of periodic orbits of autonomous systems based on high‐order extremum conditions

open access: yesMathematical Problems in Engineering, Volume 2004, Issue 3, Page 277-290, 2004., 2004
This paper gives localization and nonexistence conditions of periodic orbits in some subsets of the state space. Mainly, our approach is based on high‐order extremum conditions, on high‐order tangency conditions of a nonsingular solution of a polynomial system with an algebraic surface, and on some ideas related to algebraically‐dependent polynomials ...

Periodic solutions and stability for a delayed discrete ratio‐dependent predator‐prey system with Holling‐type functional response

open access: yesDiscrete Dynamics in Nature and Society, Volume 2004, Issue 2, Page 325-343, 2004., 2004
The existence of positive periodic solutions for a delayed discrete predator‐prey model with Holling‐type‐III functional response N1(k+1)=N1(k)exp{b1(k)-a1(k)N1(k-[τ1])-α1(k)N1(k)N2(k)/(N12(k)+m2N22(k))}, N2(k+1)=N2(k)exp{-b2(k)+α2(k)N12(k-[τ2])/(N12(k-[τ2])+m2N22(k-[τ2]))} is established by using the coincidence degree theory.

Periodic solution for ϕ-Laplacian neutral differential equation

open access: yesOpen Mathematics, 2019
This paper is devoted to the existence of a periodic solution for ϕ-Laplacian neutral differential equation as follows (ϕ(x(t)−cx(t−τ))′)′=f(t,x(t),x′(t)).$$\begin{array}{} (\phi(x(t)-cx(t-\tau))')'=f(t,x(t),x'(t)). \end{array}$$

Nonlinear systems with a partial Nash type equilibrium

open access: yes, 2021
In this paper fixed point arguments and a critical point technique are combined leading to hybrid existence results for a system of three operator equations where only two of the equations have a variational structure.
