Periodic solutions for a class of fifth-order differential equations

Chems Eddine Berrehail, Zineb Bouslah

This study aims to provide sufficient conditions for the existence of periodic solutions of the fifth-order differential equation.

On the geometry of the tangent bundle with gradient Sasaki metric

Lakehal Belarbi, Hichem Elhendi

Let (M, g) be a n-dimensional smooth Riemannian manifold. In the present paper, the authors introduce a new class of natural metrics denoted by g^f and called gradient Sasaki…

Ghodratallah Fasihi-Ramandi, Shahroud Azami

In this paper, we consider the Heisenberg groups which play a crucial role in both geometry and theoretical physics.

Weierstrass points on modular curves X0(N) fixed by the Atkin–Lehner involutions

Mustafa Bojakli, Hasan Sankari

The authors have determined whether the points fixed by all the full and the partial Atkin–Lehner involutions W_Q on X₀(N) for N ≤ 50 are Weierstrass points or not.

Multiplicity of solutions for the discrete boundary value problem involving the p-Laplacian

Abdelrachid El Amrouss, Omar Hammouti
