This is an announcement for the paper “On the separable quotient problem for Banach spaces” by J.C. Ferrando<https://arxiv.org/find/math/1/au:+Ferrando_J/0/1/0/all/0/1>, J. Kakol<https://arxiv.org/find/math/1/au:+Kakol_J/0/1/0/all/0/1>, M. Lopez-Pellicer<https://arxiv.org/find/math/1/au:+Lopez_Pellicer_M/0/1/0/all/0/1>, W. Sliwa<https://arxiv.org/find/math/1/au:+Sliwa_W/0/1/0/all/0/1>. Abstract: While the classic separable quotient problem remains open, we survey general results related to this problem and examine the existence of a particular infinitedimensional separable quotient in some Banach spaces of vector-valued functions, linear operators and vector measures. Most of the results presented are consequence of known facts, some of them relative to the presence of complemented copies of the classic sequence spaces $c_0$ and $\ell_p$, for $1\leq p\leq\infty$. Also recent results of Argyros - Dodos - Kanellopoulos, and Sliwa are provided. This makes our presentation supplementary to a previous survey (1997) due to Mujica.
