The Minkowski problem in convex geometry concerns showing a given Borel
measure on the unit sphere is, up to perhaps a constant, some type of surface
area measure of a convex body. Two types of Minkowski problems in particular
are an active area of research: $L^p$ Minkowski problems, introduced by Lutwak
and (Lutwak,Yang, and Zhang), and weighted Minkowski problems, introduced by
Livshyts. For the latter, the Gaussian Minkowski problem, whose primary
investigators were (Huang, Xi and Zhao), is the most prevalent. In this work,
we consider weighted surface area in the $L^p$ setting. We propose a framework
going beyond the Gaussian setting by focusing on rotational invariant measures,
mirroring the recent development of the Gardner-Zvavitch inequality for
rotational invariant, log-concave measures. Our results include existence for
all $p \in \mathbb R$ (with symmetry assumptions in certain instances). We also
have uniqueness for $p \geq 1$ under a concavity assumption. Finally, we obtain
results in the so-called $small$ $mass$ $regime$ using degree theory, as
instigated in the Gaussian case by (Huang, Xi and Zhao). Most known results for
the Gaussian Minkowski problem are then special cases of our main theorems.
