The arithmetic point-count conjecture for Berglund–Hübsch Calabi–Yau orbifolds
The arithmetic point-count conjecture for Berglund–Hübsch Calabi–Yau orbifolds
Let be an Berglund–Hübsch matrix over , with , and let be a subgroup of such that . Assume
Let be the hypersurface in the weighted projective space over with weights , where is the smallest integer such that each is an integer, cut out by . Let be the orbifold , and let be any crepant resolution of . Arithmetic point-count conjecture. The number of points of is equal to .
This conjecture predicts that the point count of a crepant resolution of the Berglund–Hübsch orbifold is governed by the corresponding stringy trace. The supplied text does not state whether the conjecture is known or remains open.
