Boundary value problems for higher-order nonlinear differential equations have been important in the flexibility mechanics and engineering physics. By using a variational method $2$nth-order equation with Sturm-liouville operator depending on parameter $\lambda$, under some assumptions, we verify existence of at least three solutions when $\lambda$ lies two exactly determined open intervals, respectively. In our work, shall look local minima Euler functional correspondent to problem....
In some previous papers [1], [2], [3], [4] the authors studies Laplace type problems for lattice with different foundamental cell. We want to compute probability that a segment of random position and constant lenght intersects side cell rapresented in fig.1. 1 Main Results Let < (a)the fundamental C0 fig.1 790 D. Barilla, G.

In this paper we consider two Delone hexagonal lattices with the cell represented in gure 1 and compute probability that a segment of random position costant length (body test) intersects side lattice.
In some previous papers [9] and [10] the authors studies same Laplace problems with different fundamental cells.In this paper we consider a lattice cell represented as in figure 1 compute probability that segment of random position constant length intersects side lattice.Then prove there are values for parameters determine which determined is maximum.
In this paper, we provide sufficient conditions for the existence of at least three distinct non-negative weak solutions a perturbed three-point boundary value problem Kirchhoff-type. Our technical approach is based on variational methods. addition, examples are provided to illustrate our results.
In the previous papers, [1], [2], [3], [4], [5], [6], [7], [8], [9], authors studies some Laplace problem for different lattices. this paper we consider a regular lattice with fundamental cell an equilateral triangolar and want to determine probability that ”body test” intersects side of lattice.

We investigate the existence of multiple solutions for perturbed nonlocal fourth-order equations Kirchhoff type under Navier boundary conditions. give some new criteria guaranteeing that have at least three weak by using a variational method and critical point theorems due to Ricceri. extend improve recent results. Finally, presenting two examples, we ensure applicability our
We continue the study of discrete anisotropic equations and we will provide new multiplicity results solutions for a equation. investigate existence infinitely many perturbed boundary value problem. The approach is based on variational methods critical point theory.
In this paper, we establish the existence of solutions and multiplicity properties for generalized Yamabe equations on Riemannian manifolds. Problems type arise in conformal geometry, astrophysics, theories thermionic emission, isothermal stationary gas sphere, combustion. The abstract results paper are illustrated with Emden-Fowler involving sublinear terms at infinity. Two examples reveal analytic setting paper.
