In this work we study the asymptotic behavior to positive solutions of the following coupled elliptic system of nonlinear Schrödinger equations which are defined in the punctured unit ball B1(0)\{0} for n ≥ 3. Here g is ...

In this thesis we study the existence of solutions for a class of semilinear Schr¨odinger equations of the form − u + V (x)u = ¯ f(x, u), x ∈ RN, where N ≥ 2, the potential V is a 1-periodic continuous function. In ...

The main goal of this thesis is to present a generalization of the important invariant of the singularity theory, called the Milnor number. Such generalization is what we call the logarithmic Milnor number. As well as to ...

This work is divided into three parts. In the first part, we study constant mean or scalar curvature hypersurfaces immersed into Riemannian or Lorentzian space forms satisfying a suitable Okumura type inequality. Precisely, ...

In this work we prove the existence and regularity of the global attractors and the pullback attractors for a class of autonomous and non-autonomous thermoelastic systems, respectively, with vanishing mean value for ...

In this work, we aim to prove the existence of positive solution for some nonlocal elliptic problems via bifurcation theory, more precisely by the Global Bifurcation Theorem due to Rabinowitz, where such problems are related ...

In this work we present rigidity and uniqueness results for parabolic and stable constant mean curvature hypersurfaces immersed in Generalized Robertson-Walker and Satandard Static spacetimes. We obtained some conditions ...

In this thesis, we study controllability results of some phenomena modeled by Partial Differential Equations (PDEs): > Multi objective control problem, for parabolic equations, following the Stackelber-Nash strategy is ...

In this thesis we presents results on the exact controllability of the partial Differential Equations (PDEs) of the parabolic and hyperbolic type, in the context of hierarchic control, using the Stackelberg-Nash strategy. ...
