Frequency-shifting-based stable on-line algebraic parameter identification of linear systems
Autor: Tihomir Zilic, Vladimir Milić, Josip Kasać, Andrej Jokić
Publikováno v: Journal of the Franklin Institute. 355:9224-9244
In this paper a new approach to algebraic parameter identification of the linear SISO systems is proposed. The standard approach to the algebraic parameter identification is based on the algebraic derivatives in Laplace domain as the main tool for al

The maximum number and its distribution of singular points for parametric piecewise algebraic curves
Autor: Jinming Wu, Chun-Gang Zhu
Publikováno v: Journal of Computational and Applied Mathematics. 329:322-330
The piecewise algebraic curve, as the zero set of a bivariate spline function, is a generalization of the classical algebraic curve. Based on the previous method presented by Lai et al. (2009), we show that computing singular points of parametric pie

The possible orders of growth of solutions to certain linear differential equations near a singular point
Autor: Saada Hamouda
Publikováno v: Journal of Mathematical Analysis and Applications. 458:992-1008
In this paper, we give the possible orders of growth of solutions to certain linear differential equations near a finite singular point. For that, an asymptotic equality of Wiman–Valiron type is proved for the derivatives of functions which are ana

Algebraic Parameter Estimation Using Kernel Representation of Linear Systems * *This work was supported by The National Science and Engineering Research Council of Canada
Autor: Kumar Gopalakrishnan, Debarshi Patanjali Ghoshal, Hannah Michalska
Publikováno v: IFAC-PapersOnLine. 50:12898-12904
This work makes a contribution to algebraic parameter estimation as it proposes a simple alternative to the derivation of the algebraic estimation equations. The idea is based on a system representation in the form of an evaluation functional which d

Tangents to Chow groups: on a question of Green–Griffiths
Autor: Jerome William Hoffman, Benjamin F. Dribus, Sen Yang
Publikováno v: Bollettino dell'Unione Matematica Italiana. 11:205-244
We examine the tangent groups at the identity, and more generally the formal completions at the identity, of the Chow groups of algebraic cycles on a nonsingular quasiprojective algebraic variety over a field of characteristic zero. We settle a quest

What is numerical algebraic geometry?
Autor: Andrew J. Sommese, Jonathan D. Hauenstein
Publikováno v: Journal of Symbolic Computation. 79:499-507
The foundation of algebraic geometry is the solving of systems of polynomial equations. When the equations to be considered are defined over a subfield of the complex numbers, numerical methods can be used to perform algebraic geometric computations

Locally trivial 𝔾a−actions on ℂ5 with singular algebraic quotients
Autor: Imad Jaradat, David R. Finston
Publikováno v: Communications in Algebra. 45:4992-5001
Simple examples are given of proper algebraic actions of the additive group of complex numbers on ℂ5 whose geometric quotients are, respectively, affine, strictly quasiaffine, and algebraic spaces which are not schemes. Moreover, a Zariski locally

For studying the stress-strain state at singular points and their neighborhoods new concept is proposed. A singular point is identified with an elementary volume that has a characteristic size of the real body representative volume. This makes it pos
