Class-Uniformly Resolvable Group Divisible Structures II: Frames.
We consider Class-Uniformly Resolvable frames (CURFs), which are group divisible designs with partial resolution classes subject to the class-uniform condition. We derive the necessary conditions, including extremal bounds, build the foundation for general CURF constructions, including a frame variant of the $\lambda$ blow-up construction from part I. We also establish …
