Generalised Amoeba forcing and $\Sigma^1_2$ measurability
Talk given by G.Laguzzi
Abstract
We discuss a generalized version of Amoeba forcing extending the common Amoeba for measure and Amoeba for category. In particular, we focus on a version of Amoeba for Silver which does not add Cohen reals, and we discuss some applications and open questions about $\Sigma^1_2$-measurability.
