Title: Variants and generalizations of $\Diamond^*$

Abstract: Some combinatorial principles were invented by Jensen, within his study of Godel’s constructible universe. One of them is $\Diamond^*$.

We will introduce variants and generalizations of $\Diamond^*$ and discuss when these principles hold and when they do not hold.
