Lotka-Volterra systems have been extensively studied by many authors, both in the autonomous and non-autonomous cases. In previous papers the time asymptotic behaviour as t → ∞ has been considered. In this paper we also ...

The main goal of this work is to study the existence and uniqueness of positive solution of a logistic equation including a nonlinear gradient term. In particular, we use local and global bifurcation together with some ...

In this paper we present an ACL2 formalization of a molecular computing model: Adleman’s restricted model [2]. This is a first step to formalize unconventional models of computation in ACL2. As an application of this ...

We consider a Navier-Stokes type system with a Korteweg stress tensor, coupled with a concentration equation without diffusion. We give a result concerning the local in time existence (and uniqueness) of strong solution ...

Algunos residuos agroindustriales ya compostados y usados como sustratos pueden presentar supresividad a distintas enfermedades de las plantas. Algunos de estos sustratos son el compost de corcho (usado solo o mezclado con ...

Let X be a complex analytic manifold, D ⊂ X a locally quasi-homogeneous free divisor, E an integrable logarithmic connection with respect to D and L the local system of the horizontal sections of E on X − D. In this ...

En la esquizofrenia los procesos atencionales pueden encontrarse alterados y estar a la base de otra sintomatología como los delirios y las alucinaciones. Una de las aproximaciones experimentales al estudio de los procesos ...

En el presente trabajo se realiza un análisis crítico de la influencia de Pavlov que va más allá de su visión convencional: aquélla que reduce su influencia en la psicología americana al conductismo de Watson y Hull. Para ...

In this paper we study numerically existence and stability of exact dark waves on the (nonintegrable) discrete nonlinear Schrödinger equation for a finite one-dimensional lattice. These are solutions that bifurcate from ...

In this paper our aim is to present a survey of known results of an optimal control problem with concave non-quadratic cost functional and a state equation arising from population dynamics. First, we study in detail the ...
