Effective potential for non-coupled stochastic partial differential equations
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2010)
Fisher equation for anisotropic diffusion: Simulating South American human dispersals
(American Physical Society, 2007-09)
The Fisher equation is commonly used to model population dynamics. This equation allows describing reaction-diffusion processes, considering both population growth and diffusion mechanism. Some results have been reported ...
Initial values for Riccati ODEs from variational PDEs
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2011-02)
The recently discovered variational PDEs (partial differential equations) for finding missing boundary conditions in Hamilton equations of optimal control are applied to the extended-space transformation of time-variant ...

On space-time properties of solutions for nonlinear evolutionary equations with random initial dataOn space-time properties of solutions for nonlinear evolutionary equations with random initial data
(Universidad de Costa Rica, Centro de Investigación en Matemática Pura y Aplicada (CIMPA), 1996)
High order computation of the history term in the equation of motion for a spherical particle in a fluid
(Springer/Plenum Publishers, 2004-12)
The historical evolution of the equation of motion for a spherical particle in a fluid and the search for its general solution are recalled. The presence of an integral term that is nonzero under unsteady motion and viscous ...
Large-time behavior for a fully nonlocal heat equation
(Springer, 2021-09)
We study the large-time behavior in all Lp norms and in different space-time scales of solutions to a nonlocal heat equation in ℝN involving a Caputo α-time derivative and a power of the Laplacian (−Δ)s, s ∈ (0,1), extending ...
Refractive index of binary and ternary mixtures containing propyl propanoate, heptane and octane at various temperatures
(Taylor & Francis Ltd, 2020-01-10)
Refractive index of binary and ternary liquid mixtures of propyl propanoate, heptane and octane at (283.15, 288.15, 293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K have been measured at atmospheric pressure ...
Continuous time random walks and the Cauchy problem for the heat equation
(Springer, 2018-10)
We deal with anomalous diffusions induced by continuous time random walks - CTRW in ℝn. A particle moves in ℝn in such a way that the probability density function u(·, t) of finding it in region Ω of ℝn is given by ∫Ωu(x, ...
