An improved estimate on the degree of approximation to functions of bounded variation by certain operators
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1995)
Guo introduced a modification Mn (f, x) of the Meyer-König- Zeller operators Mn (f, x) and gave an estimate on the rate of convergence to f of the modified operators when f is a function of bounded variation. In the present ...
The electronic chemical potential as a basis for a cluster model approximation for intercalation of Li in 1T - TiS2
(1995)
The representation of the electronic structure of intercalated 1T - TiS2 with lithium by a cluster approximation is discussed. The electronic chemical potential, defined in the context of density functional theory, is used ...
A probabilistic interpretation and stochastic particle approximations of the 3-dimensional Navier-Stokes equations
(SPRINGER, 2006-09)
We develop a probabilistic interpretation of local mild solutions of the three dimensional Navier-Stokes equation in the L-p spaces, when the initial vorticity field is integrable. This is done by associating a generalized ...
Faces and Support Functions for the Values of Maximal Monotone Operators
(Springer, 2020)
Representation formulas for faces and support functions of the values of maximal monotone operators are established in two cases: either the operators are defined on reflexive and locally uniformly convex real Banach spaces ...
Adiabaticity and gravity theory independent conservation laws for cosmological perturbations
(Elsevier, 2016)
We carefully study the implications of adiabaticity for the behavior of cosmological perturbations. There are essentially three similar but different definitions of non-adiabaticity: one is appropriate for a thermodynamic ...
On the SCF theory of continuum solvent effects representation: Introduction of local dielectric effects
(Wiley, 1985)
The introduction of local dielectric effects within the SCF theory of continuum solvent effects representation is examined at a semiempirical level. The formalism is developed in the frame of the reaction field theory ...
Breaking symmetries to rescue sum of squares in the case of makespan scheduling
(Springer, 2020)
The sum of squares (SoS) hierarchy gives an automatized technique to create a family of increasingly tight convex relaxations for binary programs. There are several problems for which a constant number of rounds of this ...
Cumulative effects in inflation with ultra-light entropy modes
(Institute of Physics Publishing, 2017)
In multi-field inflation one or more non-adiabatic modes may become light, potentially inducing large levels of isocurvature perturbations in the cosmic microwave background. If in addition these light modes are coupled ...
Application of PHT-splines in bending and vibration analysis of cracked Kirchhoff-Love plates
(Elsevier, 2020)
In this work, we present an eXtended Geometry Independent Field approximaTion (X-GIFT) formulation for cracked Kirchhoff-Love plates. The plate geometry is modeled by Non-Uniform Rational B-Splines (NURBS) while the solution ...
The Fukui Potential and the Capacity of Charge and the Global Hardness of Atoms
(AMER CHEMICAL SOC, 2011-02-25)
In the course of a reaction it is the shape of the Fukui potential that guides a
distant reagent toward the site where an electrophile/nucleophile is willing to accept/
donate charge. In this paper we explore the ...
