Barycentric Lagrange Interpolation

open access: yes, 2002
Barycentric interpolation is a variant of Lagrange polynomial interpolation that is fast and stable. It deserves to be known as the standard method of polynomial interpolation.\ud \ud Dedicated to the memory of Peter Henrici (1923 ...

Optimal Lagrange interpolation by quartic C¹ splines on triangulations

open access: yes, 2007
We develop a local Lagrange interpolation scheme for quartic C1 splines on triangulations. Given an arbitrary triangulation Δ, we decompose Δ into pairs of neighboring triangles and add “diagonals” to some of these pairs. Only in exceptional cases, a few

An Empirical Analysis of Institutional Coevolution in the European Union

open access: yesKyklos, EarlyView.
ABSTRACT Institutional effectiveness is widely considered an important factor for the success of the European integration process. The article investigates how the coevolution of formal and informal institutions influenced economic performance within the European Union from 1980 to 2019.

A hierarchical access control scheme based on Lagrange interpolation for mobile agents

open access: yesInternational Journal of Distributed Sensor Networks, 2018
The mobile agent is functioning as an information exchanger with hosts. In order to reduce the communication time that the host sent to the members of a large system.

q-identities from Lagrange and Newton interpolation

open access: yes, 2003
Combining Newton and Lagrange interpolation, we give q-identities which generalize results of Van Hamme, Uchimura, Dilcher, and ...

The Optimal Mean–Variance Selling Problem With Finite Horizon

open access: yesMathematical Finance, EarlyView.
ABSTRACT The optimal mean–variance selling problem seeks to determine a dynamically optimal stopping time in the nonlinear problem sup0≤τ≤TE(Xτ)−cVar(Xτ)$\sup _{0 \le \tau \le T} \left[ \mathsf {E}\,\!(X_\tau) - c\, \mathsf {V}ar\,\!(X_\tau) \right]$, where X$X$ is a geometric Brownian motion with strictly positive drift, the supremum is taken over ...

Transfinite Elements Using Bernstein Polynomials

open access: yesAxioms
Transfinite interpolation, originally proposed in the early 1970s as a global interpolation method, was first implemented using Lagrange polynomials and cubic Hermite splines.

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

open access: yesMathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Biorthogonality of the Lagrange interpolants

open access: yesJournal of Computational and Applied Mathematics, 2004
We show that the Lagrange interpolation polynomials are biorthogonal with respect to a set of rational functions whose poles coinicde with interpolation ...
