Abstract

We study a strengthening of MM++\mathrm{MM}^{++} which is called MM,++\mathrm{MM}^{\ast, ++} and which was introduced by Asper\'o and Schindler. We force its bounded version MMc,++\mathrm{MM}^{\ast, ++}_{\mathfrak{c}}, which is stronger than both MM++(c)\mathrm{MM}^{++}(\mathfrak{c}) as well as BMM++\mathrm{BMM}^{++}, by Pmax\mathbb{P}_{\max} forcing over a determinacy model LFuB(R,\mboxHom)L^{F_{\mathrm{uB}}}({\mathbb R}^*,\mbox{Hom}^{\ast}). The construction of the ground model LFuB(R,\mboxHom)L^{F_{\mathrm{uB}}}({\mathbb R}^{\ast},\mbox{Hom}^{\ast}) builds upon Gappo and Sargsyan, and the derived model construction of Larson, Sargsyan, and Wilson.
