Miniversal deformations of observable marked matrices
(2012)
Report de recerca
Accés obertGiven the set of vertical pairs of matrices M¿ Mm,n(C)×Mn(C) keeping the subspace Cd×{0} ¿ Cn invariant, we compute miniversal deformations of a given pair when it is observable and the subspace Cd × {0} is marked. ... -
Perturbation analysis of a matrix differential equation ¿x=ABx
(UP4, Institute of Sciences, S.L., 2018)
Article
Accés restringit per política de l'editorialTwo complex matrix pairs (A,B) and (A',B') are contragrediently equivalent if there are nonsingular S and R such that (A',B')=(S-1AR,R-1BS). M.I. García-Planas and V.V. Sergeichuk (1999) constructed a miniversal deformation ... -
Perturbations preserving conditioned invariant subspaces
(2010)
Comunicació de congrés
Accés obertGiven the set of matrix pairs M ⊂ Mm,n(C) × Mn(C) keeping a subspace S ⊂ Cn invariant, we obtain a miniversal deformation of a pair belonging to an open dense subset of M. It generalizes the known results when S is a ...
