Shiffman–Zelditch's finiteness conjecture for Calabi volume of Bergman spaces

About 2 years old · traced to

Let MM be a projective manifold, let LL be a very ample line bundle on MM, and for each k∈Nk\in\mathbb{N} let BM,Lk\mathcal{B}_{M,L^k} be the corresponding Bergman space with Calabi volume measure μCa\mu_{Ca}. Shiffman–Zelditch's finiteness conjecture. The Calabi volume

μCa(BM,Lk)\mu_{Ca}(\mathcal{B}_{M,L^k})

is finite for each kk. The conjecture concerns the total volume of the finite-dimensional Bergman space equipped with the metric induced by the Calabi metric. The paper exhibits polarized manifolds with non-compact automorphism groups for which this volume is infinite, so the conjecture as stated is refuted.
