Building Models of Determinacy from Below

We present an $L$-like construction that produces the minimal model of $\mathsf{AD}_\mathbb{R}+$"$\Theta$ is regular". In fact, our construction can produce any model of $\mathsf{AD}^++\mathsf{AD}_\mathbb{R}+V=L(\mathcal{P}(\mathbb{R}))$ in which the

Marginalia to a Theorem of Asper\'o and Schindler

Autor: Kasum, Obrad, Veličković, Boban

We give a game-theoretic characterization of when a model of an infinitary propositional formula can be added by a proper, semiproper, and stationary-set-preserving poset. In the latter case, we also give a general sufficient condition for the existe

Local Definability of $\mathsf{HOD}$ in $L(\mathbb{R})$

Autor: Kasum, Obrad

We show that in $L(\mathbb{R})$, assuming large cardinals, $\mathsf{HOD} {\parallel}\eta^{+\mathsf{HOD}}$ is locally definable from $\mathsf{HOD} {\parallel}\eta$ for all $\mathsf{HOD}$-cardinals $\eta\in [\boldsymbol{\delta}^2_1,\Theta)$. This is a

Iterating Semi-proper Forcing using Virtual Models

Autor: Kasum, Obrad, Veličković, Boban

By a virtual model, we mean a model of set theory which is elementary in its transitive closure. Virtual models are first used by Neeman \cite{neeman2014forcing} to iterate forcing. That paper is concerned with proper forcing. The method was then adj
