A Note on Opial Type Finite Difference Inequalities [PDF]

, 2015
[[abstract]]In the present note we establish two new Opial type finite difference inequalities involving sequences of real valued functions and their forward differences. The proofs given here are elementary and our results provide new estimates on these

Rotational Surfaces in Terms of Coordinate Finite Chen II-Type

Pan-American Journal of Mathematics
In this study, we first establish several formulae according to the first and second Beltrami operators. We discuss the class of surfaces of revolution in the 3-dimensional Euclidean space E3 without parabolic points, in which the position vector X ...

GAFA Geometric And Functional Analysis FINITE JET DETERMINATION OF LOCAL ANALYTIC CR AUTOMORPHISMS AND THEIR PARAMETRIZATION BY 2-JETS IN THE FINITE [PDF]

, 2014
We show that germs of local real-analytic CR automorphisms of a real-analytic hypersurface M in C 2 at a point p ∈ M are uniquely determined by their jets of some finite order at p if and only if M is not Levi-flat near p.

On Godunov-type finite volume methods for seismic wave propagation

Discover Geoscience
The computational complexity of simulating seismic waves demands continual exploration of more efficient numerical methods. While Finite Volume methods are widely acclaimed for tackling general nonlinear hyperbolic (wave) problems, their application in ...

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Finite element method using vector finite elements applied to eddy current problems [PDF]

, 2011
Vector fields found in electromagnetics are fundamentally different to vector fields found in other research areas such as structural mechanics. Electromagnetic vector fields possess different physical behaviour patterns and different properties in ...

Finite Cohen -Macaulay type [PDF]

, 2000
Let (R, [special characters omitted]) be a (commutative Noetherian) local ring of Krull dimension d. A non-zero R-module M is maximal Cohen-Macaulay (MCM) provided it is finitely generated and there exists an M-regular sequence x 1,…,xd in the maximal ...

Adjustment of the Auxiliary Variable(s) for Estimation of a Finite Population Mean [PDF]

In this paper we have worked to weight and transform various estimators by Prasad (1986) and Lui (1991). We have introduced some ratio and ratio type estimators under weighting, transformation and model based approach, environment.

The complexity of the dual bases for Gauss normal bases of type (n,k)(k\geq 3) over finite fields

四川大学学报. 自然科学版, 2016
It is well known that normal bases over finite fields have been implemented efficiently in software. The hardware and time complexity of multiplication using normal bases depends on the structure of the normal basis used, particularly on the complexity ...
