Existence of insensitizing controls for a semilinear heat equation with a superlinear nonlinearity
(Taylor & Francis, 2004)
In this paper we consider a semilinear heat equation (in a bounded domain Ω of IRN ) with a nonlinearity that has a superlinear growth at infinity. We prove the existence of a control, with support in an open set ω ⊂ Ω, ...

Algunos modelos estacionarios de dinámica de poblaciones estructurados en edad con difusión
(2004)
En este trabajo, daremos algunos resultados de existencia y unicidad de solución para un problema de dinámica de poblaciones estructurado en edad con difusión. Primero describiremos un método de sub-supersolución para este ...

An eigenvalue problem for non-bounded quasi-linear operator
(Cambridge University Press, 2004-06)
In this paper we study the eigenvalues associated with a positive eigenfunction of a quasilinear elliptic problem with a not necessarily bounded operator. For that, we use the bifurcation theory and obtain the existence ...

A local result on insensitizing controls for a semilinear heat equation with nonlinear boundary Fourier conditions
(Society for Industrial and Applied Mathematics, 2004)
In this paper we present a local result on the existence of insensitizing controls for a semilinear heat equation when nonlinear boundary conditions of the form ∂ny + f(y)=0 are considered. The problem leads to an analysis ...

Reduced bootstrap for the median
(Academia Sinica (Institute of Statistical Science), 2004-10)
In this paper we study a modified bootstrap that consists of only considering those bootstrap samples satisfying k1 ≤ νn ≤ k2, for some 1 ≤ k1 ≤ k2 ≤ n, where νn is the number of distinct original observations in the ...

A note on a degenerate elliptic equation with applications for lakes and seas
(Texas State University, 2004)
In this paper, we give an intermediate regularity result on a degenerate elliptic equation with a weight blowing up on the boundary. This kind of equations is encountoured when modelling some phenomena linked to seas or ...
