Democracy of quasi-greedy bases in p-Banach spaces with applications to the efficiency of the thresholding greedy algorithm in the hardy spaces Hp(Dd)
Albiac Alesanco, Fernando José ; Ansorena, José L.; Bello, Glenier (Cambridge University Press, 2023) Artículo / ArtikuluaWe use new methods, specific for non-locally convex quasi-Banach spaces, to investigate when the quasi-greedy bases of a -Banach space for 0 < p < p are democratic. The novel techniques we obtain permit to show in particular ... -
Existence of almost greedy bases in mixed-norm sequence and matrix spaces, including besov spaces
Albiac Alesanco, Fernando José ; Ansorena, José L.; Bello, Glenier; Wojtaszczyk, Przemyslaw (Springer, 2023) Artículo / ArtikuluaWe prove that the sequence spaces lp ⊕ lq and the spaces of infinite matrices lp(lq ), lq l(p) and ( ∞ n=1 n lp)lq , which are isomorphic to certain Besov spaces, have an almost greedy basis whenever 0 < p < 1 < q < ∞. ...
