Non-trivial, non-negative periodic solutions of a system of singular-degenerate parabolic equations with nonlocal terms [PDF]
We study the existence of non-trivial, non-negative periodic solutions for systems of singular-degenerate parabolic equations with nonlocal terms and satisfying Dirichlet boundary conditions.

High-energy solutions for coupled Schrödinger systems with critical growth and lack of compactness
This article deals with the existence of high-energy positive solutions for the following coupled Schrödinger system with critical exponent: −Δu+V1(x)u=μ1u3+βuv2,x∈Ω,−Δv+V2(x)v=βu2v+μ2v3,x∈Ω,u,v∈D01,2(Ω)\left\{\begin{array}{l}-\Delta u+{V}_{1}\left(x)u={\

Separable solutions of quasilinear Lane-Emden equations [PDF]
For $0 < p-1 < q$ and $\ge=\pm 1$, we prove the existence of solutions of $-\Gd_pu=\ge u^q$ in a cone $C_S$, with vertex 0 and opening $S$, vanishing on $\prt C_S$, under the form $u(x)=|x|^\gb\gw(\frac{x}{|x|})$.

Existence, nonexistence and multiplicity results for some beam equations [PDF]
This paper studies some fourth order nonlinear fully equations with a parameter s ∈ R, with two point boundary conditions. These problems model several phenomena, such as, a cantilevered beam with a linear relation between the curvature and the shear ...

T-periodic dynamics in a 3D delayed quasispecies model
We study periodic dynamics and error-threshold behavior in a delayed quasispecies model consisting of a master sequence [Formula: see text] and two mutant populations [Formula: see text].

A Hartman-Nagumo type condition for a class of contractible domains [PDF]
We generalize an existence result on second order systems with a nonlinear term satisfying the so-called Hartman-Nagumo condition. The generalization is based on the use of Gauss second fundamental form and continuation techniques.Fil: Amster, Pablo ...

Nontrivial solutions of quasilinear elliptic equations with natural growth term
We prove the existence of multiple solutions for a quasilinear elliptic equation containing a term with natural growth, under assumptions that are invariant by diffeomorphism.

Nonlinear Variational Inequalities Depending on a Parameter [PDF]
This paper develops the results announced in the Note [14]. Using an eigenvalue problem governed by a variational inequality, we try to unify the theory concerning the post-critical equilibrium state of a thin elastic plate subjected to unilateral ...
