Counterexamples in isometric theory of symmetric and greedy bases
Fernando Albiac, Jose L. Ansorena, Oscar Blasco +2
We continue the study initiated in [F. Albiac and P. Wojtaszczyk, Characterization of -greedy bases, J. Approx. Theory 138 (2006), no. 1, 65-86] of properties related to greedy…
Notes on bilinear multipliers on Orlicz spaces
Oscar Blasco, Alen Osancliol
Let and be Young functions and let , and be the corresponding Orlicz spaces. We say that a func…
Lebesgue inequalities for Chebyshev Thresholding Greedy Algorithms
Pablo M. Berná, Oscar Blasco, Gustavo Garrigós +2
We establish estimates for the Lebesgue parameters of the Chebyshev Weak Thresholding Greedy Algorithm in the case of general bases in Banach spaces. These generalize and slightly…
A class of Schur multipliers of matrices with operator entries
O. Blasco, I. García-Bayona
In this paper, we will consider matrices with entries in the space of operators , where is a separable Hilbert space, and consider the class of (left or right)…
New spaces of matrices with operator entries
O. Blasco, I. García-Bayona
In this paper, we will consider matrices with entries in the space of operators , where is a separable Hilbert space and consider the class of matrices that can…
Schur product with operator-valued entries
O. Blasco, I. García-Bayona
In this paper we characterize Toeplitz matrices with entries in the space of bounded operators on Hilbert spaces which define bounded operators acting on $\ell^2(H…
