A Universe with large Continuum, global $Σ$-Uniformization and a projective Well-Order of its Reals

Abstract: We construct a model in which the continuum has size $\kappa$ for a regular cardinal $\kappa$ and in which the $\Sigma^1_n$-uniformization property holds simultaneously for every $n \ge 2$. Additionally this model has a $\Delta^1_3$- definable well-order of its reals.
