On forcing over \(L(\mathbb{R})\). (English) Zbl 07680028

Summary: Given that \(L(\mathbb{R})\models\text{ZF}+\text{AD}+\text{DC}\), we present conditions under which one can generically add new elements to \(L(\mathbb{R})\) and obtain a model of \(\text{ZF}+\text{AD}+\text{DC}\). This work is motivated by the desire to identify the smallest cardinal \(\kappa\) in \(L(\mathbb{R})\) for which one can generically add a new subset \(g\subseteq\kappa\) to \(L(\mathbb{R})\) such that \(L(\mathbb{R})(g)\models\text{ZF}+\text{AD}+\text{DC}\).
