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…
