Abstract:
We prove the consistency of: for suitable strongly inaccessible cardinal $\lambda$ the dominating number, i.e., the cofinality of ${}^\lambda \lambda$, is strictly bigger than cov$_\lambda$(meagre), i.e., the minimal number of nowhere dense subsets of ${}^\lambda 2$ needed to cover it. This answers a question of Matet.References
