Formalization and Implementation of Algebraic Methods in Geometry [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
We describe our ongoing project of formalization of algebraic methods for geometry theorem proving (Wu's method and the Groebner bases method), their implementation and integration in educational tools.

Solution Bounds and Numerical Methods of the Unified Algebraic Lyapunov Equation

open access: yesMathematics, 2022
In this paper, applying some properties of matrix inequality and Schur complement, we give new upper and lower bounds of the solution for the unified algebraic Lyapunov equation that generalize the forms of discrete and continuous Lyapunov matrix ...

A Computer Algebra System for R: Macaulay2 and the m2r Package

open access: yesJournal of Statistical Software, 2020
Algebraic methods have a long history in statistics. Apart from the ubiquitous applications of linear algebra, the most visible manifestations of modern algebra in statistics are found in the young field of algebraic statistics, which brings tools from ...

Nontrivial solutions of linear functional equations: methods and examples [PDF]

open access: yesOpuscula Mathematica, 2015
For a wide class of linear functional equations the solutions are generalized polynomials. The existence of non-trivial monomial terms of the solution strongly depends on the algebraic properties of some related families of parameters.

Algebraic Methods for Traffic Flow Densities Estimation

open access: yesCybernetics and Information Technologies, 2013
An estimation approach that allows recovering of the traffic state is proposed in this paper. The method used is based on numerical differentiation, which does not need any integration of differential equations and turns out to be quite robust with ...

A Granular Computing Based Classification Method From Algebraic Granule Structure

open access: yesIEEE Access, 2021
Classification, as one of the main task of machine learning, corresponds to the core work of granular computing, namely granulation. Most of granular computing models and related classification methods are uniquely classifying by granule features, but ...

Computational algebraic methods in efficient estimation

open access: yes, 2014
A strong link between information geometry and algebraic statistics is made by investigating statistical manifolds which are algebraic varieties. In particular it it shown how first and second order efficient estimators can be constructed, such as bias ...

Stochastic Runge–Kutta methods for multi-dimensional Itô stochastic differential algebraic equations

open access: yesResults in Applied Mathematics, 2021
In this paper, we discuss the numerical solutions to index 1 stochastic differential algebraic equations. We introduce a new class of weak second-order stochastic Runge–Kutta methods for finding the numerical approximate solutions to multi-dimensional ...

Algebraic Methods in the Congested Clique

open access: yes, 2015
In this work, we use algebraic methods for studying distance computation and subgraph detection tasks in the congested clique model. Specifically, we adapt parallel matrix multiplication implementations to the congested clique, obtaining an $O(n^{1-2 ...

Algebraic Multilevel Preconditioning Methods, II

open access: yesSIAM Journal on Numerical Analysis, 1989
A recursive way of constructing preconditioning matrices for the stiffness matrix in the discretization of selfadjoint second order elliptic boundary value problems is proposed. It is based on a sequence of nested finite element spaces with the usual nodal basis functions.
