A New Upper Bound for the d-dimensional Algebraic Connectivity of Arbitrary Graphs
Juan F. Presenza, Ignacio Mas, Juan I. Giribet +1
In this paper we show that the -dimensional algebraic connectivity of an arbitrary graph is bounded above by its -dimensional algebraic connectivity, i.e., $a_d(G) \leq a…
Learning-Based Fault-Tolerant Control for an Hexarotor with Model Uncertainty
Leonardo J. Colombo, Manuela Gamonal Fernandez, Juan I. Giribet
In this paper we present a learning-based tracking controller based on Gaussian processes (GP) for a fault-tolerant hexarotor in a recovery maneuver. In particular, to estimate cer…
Spectral enclosures for a class of block operator matrices
Juan Giribet, Matthias Langer, Francisco Martínez Pería +2
We prove new spectral enclosures for the non-real spectrum of a class of block operator matrices with self-adjoint operators and on the diagonal and operators $B…
On a class of non-Hermitian matrices with positive definite Schur complements
Thomas Berger, Juan Ignacio Giribet, Francisco Martínez Pería +1
Given a positive definite matrix and a Hermitian matrix , we characterize under which conditions there exists a strictly…
Shorted operators and minus order
Maximiliano Contino, Juan Ignacio Giribet, Alejandra Maestripieri
Let be a Hilbert space, the algebra of bounded linear operators on and a positive operator. Given a closed subsp…
Duality for Frames in Krein Spaces
J. I. Giribet, A. Maestripieri, Francisco Martínez Pería
A -frame for a Krein space is in particular a frame for (in the Hilbert space sense). But it is also compatible with the indefinite inner-product of…
