الوصف: For a polarized family of complex projective manifolds, we study the Hermitian Yang-Mills functionals on the sequence of vector bundles over the base of the family associated with direct image sheaves of the tensor powers of the polarization. We make a connection between the asymptotic minimization of these functionals, for big tensor powers of the polarization, and the minimization of the so-called Wess-Zumino-Witten functional defined on the space of all relatively K\"ahler $(1, 1)$-forms on the fibration. We establish the sharp lower bounds on the latter functional in terms of the limiting Harder-Narasimhan measure, which is a certain algebraic invariant of the family. As an application, in a fibered setting, we prove an asymptotic converse to the Andreotti-Grauert theorem conjectured by Demailly.
