The Decomposition Theorem of Beilinson–Bernstein–Deligne-Gabber states that
$$Rf∗IC_X \cong \oplus_a IC_{\bar{Y_a}}(L_a)[shifts]$$
My question is: what are some interesting classes of examples maps … Right now I could only think of examples like finite branched coverings of projective spaces, $f: \mathbb{P}^1 \rightarrow \mathbb{P}^1$ such that $z$ gets mapped to $z^n$ for some positive integer $n$ …
