[Banach] Abstract of a paper by Longyun Ding and Zhi Yin

This is an announcement for the paper "Borel equivalence relations between \ell_1 and \ell_p" by Longyun Ding and Zhi Yin. Abstract: In this paper, we show that, for each $p>1$, there are continuum many Borel equivalence relations between $\Bbb R^\omega/\ell_1$ and $\Bbb R^\omega/\ell_p$ ordered by $\le_B$ which are pairwise Borel incomparable.
