Scalar field equation with non-local diffusion
(Springer, 2015)
In this paper we are interested on the existence of ground state solutions for fractional field equations of the form
integral (I - Delta)(alpha) u = f(x, u) in IRN, u > 0 in IRN, lim(vertical bar x vertical bar ...
Pulsating fronts for nonlocal dispersion and KPP nonlinearity
(Elsevier, 2013)
In this paper we are interested in propagation phenomena for nonlocal reaction–diffusion equations of the type:
∂u
∂t = J ∗ u −u+ f (x,u) t ∈ R, x ∈ RN,
where J is a probability density and f is a KPP nonlinearity ...
Interaction between vegetation patches and gaps: A self-organized response to wáter scarcity
(Elsevier, 2020)
The dynamics of ecological systems are often described by integrodifferential equations that incorporate nonlocal interactions associated with facilitative, competitive interactions between plants, and seed dispersion. In ...
Sweeping by a tame process
(Centre de diffusion des revues académiques de mathématiques, 2017)
We show that any semi-algebraic sweeping process admits piecewise
absolutely continuous solutions (trajectories), and any such bounded trajectory
must have finite length. Analogous results hold more generally for ...
Elution relationships to model affinity chromatography using a general rate model
(John Wiley & Sons, 2012-08-21)
Differentmathematicalmodels with different degrees of complexity have been proposed to model affinity chromatography.
In this work, in particular, a general rate model has been studied that considers axial dispersion, ...
Real-Time Tracking of Phytochrome's Orientational Changes During Pr Photoisomerization
(AMER CHEMICAL SOC, 2012)
Photoisomerization of a protein bound chromophore is the basis of the light sensing and signaling responses of many photoreceptors. Z-to-E photoisomerization of the Pr Cph1 Delta 2 phytochrome has been investigated by ...
Desolvation effects on the dissociation energy of diatomic molecules:Ab initio study of the dissociation of Li-F in polar media
(Springer-Verlag, 1993)
The potential curve of the ground state dissociation of Li-F in water has been studied by a combination of a standard ab initio Hartree-Fock procedure and a perturbative reaction field approach. The electrostatic solute-solvent ...
Subordination principle, Wright functions and large-time behavior for the discrete in time fractional diffusion equation
(Academic Press Inc.United States, 2022)
Política y crecimiento económico en Colombia, 1906-2009
(Universidad Externado de Colombia, 2014-12-05)
El activo público más importante para el crecimiento económico colombiano ha sido la diversificación de la industria manufacturera. Los gobiernos que han promovido este y otros activos productivos (especialmente la ...
Valoración de opciones financieras call en contexto de no normalidad, bajo la aproximación de Edgeworth
(Facultad de Finanzas, Gobierno y Relaciones Internacionales, 2021-06-08)
El modelo de Black-Scholes es el método universal para la valoración de opciones financieras. Sin embargo, este modelo presenta varias deficiencias que hacen que, al contrastar sus resultados con los precios de mercado ...
