Approximation order and approximate sum rules in subdivision

Journal of Approximation Theory, 2016
Several properties of stationary subdivision schemes are nowadays well understood. In particular, it is known that the polynomial generation and reproduction capability of a stationary subdivision scheme is strongly connected with sum rules, its convergence, smoothness and approximation order.

Dispersive properties of high order nedelec/edge element approximation of the time-harmonic Maxwell equations [PDF]

, 2004
The dispersive behaviour of high-order Næ#169;dæ#169;lec element approximation of the time harmonic Maxwell equations at a prescribed temporal frequency ω on tensor-product meshes of size h is analysed.

A note on the polynomial approximation of vertex singularities in the boundary element method in three dimensions [PDF]

, 2008
We study polynomial approximations of vertex singularities of the type $r^\lambda |\log r|^\beta$ on three-dimensional surfaces. The analysis focuses on the case when $\lambda > -\frac 12$.

Approximate Partial Order Reduction [PDF]

, 2018
We present a new partial order reduction method for reachability analysis of nondeterministic labeled transition systems over metric spaces. Nondeterminism arises from both the choice of the initial state and the choice of actions, and the number of executions to be explored grows exponentially with their length.

Second order approximations for limit order books [PDF]

Finance and Stochastics, 2018
In this paper we derive a second order approximation for an infinite dimensional limit order book model, in which the dynamics of the incoming order flow is allowed to depend on the current market price as well as on a volume indicator (e.g.~the volume standing at the top of the book).

Rational approximation of discrete data with asymptomatic behaviour [PDF]

This thesis is concerned with the least-squares approximation of discrete data that appear to exhibit asymptotic behaviour. In particular, we consider using rational functions as they are able to display a number of types of asymptotic behaviour.

Estimation of the order of the matrix method approximation of numerical integration of boundary-value problems for the second order inhomogeneous linear ordinary differential equations

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
Using the first three terms of Taylor expansion of the required function in the approximate derivative by finite differences leads to the second order approximation of the traditional numerical quadrature method of boundary value problems for linear ...

On the order of approximation in approximative triadic decompositions of tensors

Theoretical Computer Science, 1989
Based on \textit{A. Alder's} result [Grenzrang und Grenzkomplexität aus algebraischer und topologischer Sicht, Dissertation, Univ. Zürich (1984)] on the equivalence of algebraic and topological border rank of tensors t over algebraically closed ground fields k, the author gives an upper bound for the order of approximation in approximative triadic ...

Numerical integration by the matrix method of boundary value problems for linear inhomogeneous ordinary differential equations of the third order with variable coefficients
