Sum of Squares of ‘m’ Consecutive Woodall Numbers

open access: yesمجلة بغداد للعلوم, 2023
        This paper discusses the Sums of Squares of “m” consecutive Woodall Numbers. These discussions are made from the definition of Woodall numbers. Also learn the comparability of Woodall numbers and other special numbers.

On the regularity of the solutions and of analytic vectors for “sums of squares”

open access: yesBruno Pini Mathematical Analysis Seminar, 2023
We present a brief survey on some recent results concerning the local and global regularity of the solutions for some classes/models of sums of squares of vector fields with real-valued real analytic coefficients of H"ormander type.

Systematic Analysis and Design of Control Systems Based on Lyapunov’s Direct Method

open access: yesAlgorithms, 2023
This paper deals with systematic approaches for the analysis of stability properties and controller design for nonlinear dynamical systems. Numerical methods based on sum-of-squares decomposition or algebraic methods based on quantifier elimination are ...

Invariance principle for independent random variables with infinite variance

open access: yesLietuvos Matematikos Rinkinys, 2023
A functional central limit theorem for self-normalized adaptive process U−1m,N ζn is considered, where Um,N is a sum of squares of block-sums of size m, as m and the number of blocks N = n/m tend to infinity.

Sum of Squares of ‘n’ Consecutive Carol Numbers

open access: yesمجلة بغداد للعلوم, 2023
The discussion in this paper gives several theorems and lemmas on the Sums of Squares of  consecutive Carol Numbers. These theorems are proved by using the definition of carol numbers and mathematical induction method.

A Beveridge–Nelson filters for the self normalization

open access: yesLietuvos Matematikos Rinkinys, 2021
Let Xt =Σ∞i=0 ψi εt−i be a linear process, where εt , t ∈ Z, are i.i.d. r.v.’s in the domain of attraction of a normal law with zero mean and possibly infinite variance.

Sum-of-squares geometry processing [PDF]

open access: yesACM Transactions on Graphics, 2021
Geometry processing presents a variety of difficult numerical problems, each seeming to require its own tailored solution. This breadth is largely due to the expansive list of geometric primitives , e.g., splines, triangles, and hexahedra, joined with an ever-expanding variety of objectives ...

Custom Bell inequalities from formal sums of squares [PDF]

open access: yesQuantum
Bell inequalities play a key role in certifying quantum properties for device-independent quantum information protocols. It is still a major challenge, however, to devise Bell inequalities tailored for an arbitrary given quantum state.

On infinite divisibility of a class of two-dimensional vectors in the second Wiener chaos

open access: yesModern Stochastics: Theory and Applications, 2020
Infinite divisibility of a class of two-dimensional vectors with components in the second Wiener chaos is studied. Necessary and sufficient conditions for infinite divisibility are presented as well as more easily verifiable sufficient conditions.

Augmented Latin Square Designs for Imprecise Data [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
This paper addresses a novel approach for analyzing augmented Latin square design with uncertain observations, the so-called neutrosophic augmented Latin square design (NALSD). The contribution of our work lies in estimating the effects of rows, columns,
