The conjecture on asymptotic expansion of Bergman kernels
The conjecture on asymptotic expansion of Bergman kernels
Let be a smooth projective variety of dimension , let be a pseudoeffective singular Hermitian line bundle on , and let be a sufficiently ample line bundle on with a Hermitian metric of strictly positive curvature. Let and denote the upper and lower local volumes defined by the corresponding limsup and liminf of the normalized Bergman kernels.
Bergman-kernel asymptotics conjecture. The upper and lower local volumes coincide:
In particular, the normalized Bergman-kernel limit exists on , and it equals the local volume :
The claim concerns the existence and identification of pointwise asymptotics for Bergman kernels associated with pseudoeffective singular metrics. The source presents it as a general conjecture; no resolution is supplied there.
