Roots and polynomials as Homeomorphic spaces

open access: yesExpositiones Mathematicae, 2006
We provide a unified, elementary, topological approach to the classical results stating the continuity of the complex roots of a polynomial with respect to its coefficients, and the continuity of the coefficients with respect to the roots. In fact, endowing the space of monic polynomials of a fixed degree $n$ and the space of $n$ roots with suitable ...

Retrieval of Separated Instruments from Root Canal Space: A Case [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2019
Separation of nickel-titanium instrument during root canal treatment can cause serious complications that may lead to treatment failure. It prevents complete cleaning and filling of the entire root canal space. Retrieval of the instrument should be tried

PT invariant complex E(8) root spaces

open access: yesInternational Journal of Theoretical Physics, 2010
We provide a construction procedure for complex root spaces invariant under antilinear transformations, which may be applied to any Coxeter group. The procedure is based on the factorisation of a chosen element of the Coxeter group into two factors. Each of the factors constitutes an involution and may therefore be deformed in an antilinear fashion ...

Cointegration, Root Functions and Minimal Bases

open access: yesEconometrics, 2021
This paper discusses the notion of cointegrating space for linear processes integrated of any order. It first shows that the notions of (polynomial) cointegrating vectors and of root functions coincide.

Quasiinvariants of Coxeter groups and m-harmonic polynomials [PDF]

open access: yes, 2001
The space of m-harmonic polynomials related to a Coxeter group G and a multiplicity function m on its root system is defined as the joint kernel of the properly gauged invariant integrals of the corresponding generalised quantum Calogero-Moser problem ...

Root Locii for Systems Defined on Hilbert Spaces [PDF]

open access: yesIEEE Transactions on Automatic Control, 2016
The root locus is an important tool for analysing the stability and time constants of linear finite-dimensional systems as a parameter, often the gain, is varied. However, many systems are modelled by partial differential equations or delay equations.

Decay of correlations in suspension semi-flows of angle-multiplying maps [PDF]

open access: yes, 2007
We consider suspension semi-flows of angle-multiplying maps on the circle. Under a $C^r$generic condition on the ceiling function, we show that there exists an anisotropic Sobolev space contained in the $L^2$ space such that the Perron-Frobenius operator
