Skew Divided Difference Operators and Schubert Polynomials [PDF]

open access: diamondSymmetry, Integrability and Geometry: Methods and Applications, 2007
We study an action of the skew divided difference operators on the Schubert polynomials and give an explicit formula for structural constants for the Schubert polynomials in terms of certain weighted paths in the Bruhat order on the symmetric group.

Correntropy Based Divided Difference Filtering for the Positioning of Ships [PDF]

open access: goldSensors, 2018
In this paper, robust first and second-order divided difference filtering algorithms based on correntropy are proposed, which not only retain the advantages of divided difference filters, but also exhibit robustness in the presence of non-Gaussian noises,

Maximum Likelihood-Based Iterated Divided Difference Filter for Nonlinear Systems from Discrete Noisy Measurements [PDF]

open access: yesSensors, 2012
A new filter named the maximum likelihood-based iterated divided difference filter (MLIDDF) is developed to improve the low state estimation accuracy of nonlinear state estimation due to large initial estimation errors and nonlinearity of measurement ...

Divided square difference cordial Labeling of join some spider graphs [PDF]

open access: yesE3S Web of Conferences, 2023
Let G be a graph with its vertices and edges. On defining bijective function ρ:V(G) →{0,1,...,p}. For each edge assign the label with 1 if ρ*(ab)= | ρ(a)2−ρ(b)2/ρ(a)−ρ(b) | is odd or 0 otherwise such that |eρ(1) − eρ(0)| ≤ 1 then the labeling is called ...

On some properties of Schwartz–Gopengauz operator

open access: yesLietuvos Matematikos Rinkinys, 2023
The generalization of Schwarz’s derivative proposed by B.E. Gopengauz, which is applied to the study of the properties of the class of functions with nonvanishing in the unit circle divided difference of n-th order is examined.

n-Convexity via Delta-Integral Representation of Divided Difference on Time Scales

open access: yesInternational Journal of Analysis and Applications, 2022
We introduce the delta-integral representation of divided difference on arbitrary time scales and utilize it to set criteria for n-convex functions involving delta-derivative on time scales.
