摘要

We present a new variation of the classical selection principles S-k(A, B) (k is an element of N) and S-fin(A, B) that formally lies between these two properties. As in the case of the classical selection principles, we also obtain a new variation of topological game and discuss how new topological properties may emerge in the specific cases of covering and tightness.
