contents PBH formation requires high-density regions in the (random) density field filling the primordial universe. While only the largest (and so rarest) overdensities collapse to form PBHs, the rest cause large anisotropic stresses, which are the source of GWs. We provide an overview of the theoretical aspects of the GW backgrounds associated with PBHs from large primordial fluctuations. We consider GW backgrounds associated with PBH formation, PBH reheating and unresolved PBH binaries. We present several graphical summaries and illustrations for the busy reader.
