- ItemA nonlocal diffusion equation whose solutions develop a free boundary(2005) Cortazar, C; Elgueta, M; Rossi, JDLet J : R -> R be a nonnegative, smooth compactly supported function such that integral(R) J(r)dr = 1. We consider the nonlocal diffusion problem
- ItemShort time behavior near the boundary for the heat equation with a nonlinear boundary condition(2002) Cortazar, C; Elgueta, M; Rossi, JD
- ItemSymmetry in an elliptic problem and the blow-up set of a quasilinear heat equation.(MARCEL DEKKER INC, 1996) Cortazar, C; Elgueta, M; Felmer, P
- ItemUniqueness and boundary behavior of large solutions to elliptic problems with singular weights(2004) Chuaqui, M; Cortazar, C; Elgueta, M; Garcia-Melian, JWe consider the elliptic problems Deltau = a(x)u(m), m > 1, and Deltau = a(x)e(u) in a smooth bounded domain Omega, with the boundary condition u = +infinity on partial derivativeOmega. The weight function a(x) is assumed to be Holder continuous, growing like a negative power of d(x) = dist(x, partial derivativeOmega) near partial derivativeOmega. We show existence and nonexistence results, uniqueness and asymptotic estimates near the boundary for both the solutions and their normal derivatives.
- ItemUniqueness and non-uniqueness for a system of heat equations with nonlinear coupling at the boundary(1999) Cortazar, C; Elgueta, M; Rossi, JD
- ItemUniqueness of positive solutions of Δu+f(u)=0 in RN, N≥3(1998) Cortazar, C; Elgueta, M; Felmer, PWe study the uniqueness of radial ground states for the semilinear elliptic partial differential equation
