Curvature of higher direct images of sheaves of twisted holomorphic forms

This paper investigates the curvature properties of higher direct images Rqf_*ΩX/Sᵖ(E), where f: X→ S is a family of compact K\"ahler manifolds equipped with a hermitian vector bundle E → X. We derive a general curvature formula and explore several special cases, including those where $p + q = n$, $q = 0$, and $p = n$, with E being a line bundle. Furthermore, the paper examines the curvature in the context of fiberwise hermitian flat cases, families of Hermite-Einstein vector bundles, and applications to moduli spaces and Weil-Petersson metrics, providing some insight into their geometric and analytical properties.
