In this work, we discuss the existence and the non-existence of principal eigenvalue in an unbounded domain of $\mathbb{R}^ N$ for some potentials which change sign. We also give certain properties of this principal eigenvalue. [...]
We show the existence of a first curve in the Fučik spectrum with weights for the p- Laplacian under mixed boundary conditions. We also study the asymptotic behavior of this first curve. [...]
We work on the whole R N and prove the existence of a first non- principal eigenvalue for an asymmetric problem with weights involving the p-Laplacian (cf. (1.1) below). As an application we obtain a first nontrivial curve in the corresponding Fuč [...]
Let (Σ, ω) be a compact Riemann surface with constant curvature c. In this work, we proved that the mean curvature flow of a given Hamiltonian diffeomorphism on Σ provides a smooth path in Ham(Σ), the group of all Hamiltonian diffeomorphisms of Σ. [...]
In this artticle, we consider the order estimation of autoregressive modelswith incomplete data using expectation maximization(EM) algorithm based information criteria.The criteria take the form of a penalization of the conditionnal expectation of th [...]
