Abstract

This paper has three parts. In this first part, we formulate and prove from $V = L$ a new combinatorial principle, $\Diamond^{++}$. In the second part, we discuss the topological problem which led to the formulation of $\Diamond^{++}$. Finally, we use $\Diamond^{++}$ to construct a space solving the topological problem.
