Weighted generalized inverses, oblique projections and least squares problems
Gustavo Corach, Alejandra Maestripieri
A generalization with singular weights of Moore-Penrose generalized inverses of closed range operators in Hilbert spaces is studied using the notion of compatibility of subspaces a…
Fast computation of a rational point of a variety over a finite field
Antonio Cafure, Guillermo Matera
We exhibit a probabilistic algorithm which computes a rational point of an absolutely irreducible variety over a finite field defined by a reduced regular sequence. Its time--space…
Improved explicit estimates on the number of solutions of equations over a finite field
Antonio Cafure, Guillermo Matera
We show explicit estimates on the number of --rational points of an --definable affine absolutely irreducible variety of the algebraic closure of the finite field of…
The hardness of polynomial equation solving
David Castro, Marc Giusti, Joos Heintz +2
In this paper we investigate the intrinsic sequential time complexity of universal elimination procedures for arbitrary continuous data structures encoding input and output objects…
Applications of recurrence quantified analysis to study the dynamics of chaotic chemical reaction
H. Castellini, L. Romanelli
Recurrence plot is a quite easy tool to be used in time series analysis,in particular for measuring unstable periodic orbits embedded in a chaotic dynamical system. Recurrence quan…
