$L^p$ metric geometry of big and nef cohomology classes

Abstract

Let $(X,\omega)$ be a compact K\"ahler manifold of dimension $n$, and $\theta$ be a closed smooth real $(1,1)$-form representing a big and nef cohomology class. We introduce a metric $d_p, p\geq 1$, on the finite energy space $\mathcal{E}^p(X,\theta)$, making it a complete geodesic metric space.
