cardinal invariants of the continuum; splitting number; open splitting number; reaping number; $\sigma$-reaping number; Cicho'n's diagram; Hechler forcing; finite support iteration
Summary:
We prove several results on some cardinal invariants of the continuum which are closely related to either the splitting number $\mathfrak s$ or its dual, the reaping number $\mathfrak r$.
