Banach spaces webinar on Friday Oct 23 by Przemyslaw Wojtaszczyk (Polish Academy)
Dear all, The next Banach spaces webinar is on Friday October 23 9AM CDT (e.g., Dallas, TX time). Please join us at https://unt.zoom.us/j/512907580 Speaker: Przemyslaw Wojtaszczyk, Institut of Mathematics Polish Academy of Sciences Title: Quasi-greedy bases in $p$-Banach spaces Abstract: This talk is based on the paper F. Albiac, J.L. Ansorena and P.W. \emph{On certain subspaces of $\ell_p$ for $0<p\le 1$ and their applications to conditional quasi-greedy bases in $p$-Banach spaces} Mathematische Annalen--available on line. We construct new quasi-greedy bases in $\ell_p$ and in the kernels of certain quotient maps from $\ell_p $ onto $L_p$, $0<p\leq 1$ and study its properties. We note that all the kernels we study are isomorphic; we denote this space as ${\mathfrak l }_p$ . We show that there is continuum of non-equivalent quasi-greedy bases in $\ell_p$ and ${\mathfrak l }_p$ and we study the conditionality of those bases.
