Condicionamiento y alta precisión en problemas espectrales estructurados [PDF]
, 2007 Esta memoria trata dos aspectos relacionados con la precisión de algoritmos espectrales para problemas matriciales estructurados: 1) Se definen números de condición estructurados de autovalores múltiples, eventualmente defectivos, y se obtienen fórmulas ...

The role of identification in data‐driven policy iteration: A system theoretic study
International Journal of Robust and Nonlinear Control, EarlyView.Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Korobov’s controllability function method via orthogonal polynomials on [0,∞)
Visnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i MehanikaGiven a controllable system described by ordinary or partial differential equations and an initial state, the problem of finding a set of bounded positional controls that transfer the initial state to another state, not necessarily an equilibrium point ...

Star products on the algebra of polynomials on the dual of a semi-simple Lie algebra
, 1997 We show, by elementary methods, that all star products on the space of polynomials on the dual of a semi-simple Lie algebra are equivalent to the standard one and that all v-linear derivations of such star products are essentially inner.Chloup-Arnould ...

Parameterized Structure-Preserving Transformations of Matrix Polynomials
, 2020 This paper examines the relationship between the companion forms of regular matrix polynomials with singular leading coefficients. When two such polynomials have the same underlying finite and infinite Jordan structures, it is shown that their companion ...

Factorization of polynomials and some linear-algebra problems over finite fields
, 1993 The recently developed algorithm of Niederreiter for the factorization of polynomials over finite fields provides a “linearization” of the factorization problem via differential equations in rational function fields.
