Tomasz Weiss Bulletin Polish Acad. Sci. Math. 65 (2017), 107-111 MSC: Primary 03E05; Secondary 03E17. DOI: 10.4064/ba8098-8-2017 Published online: 1 September 2017


We investigate various properties of the intersection ideal $\mathcal M\cap \mathcal N$ of subsets of the reals that are related to the translations of its members. We are also concerned with cardinal coefficients associated with the ideal $\mathcal M\cap \mathcal N$.
