Minimal mld conjecture for the constructed klt Calabi–Yau varieties

For each integer n2n\geq2, let V/GV/G be the quotient of the hypersurface constructed in the paper by the cyclic group action described there; it is a klt Calabi–Yau variety of dimension nn with minimal log discrepancy 1/m1/m. Minimal mld conjecture for varieties. For every n2n\geq2, the quotient V/GV/G has the smallest minimal log discrepancy among all klt Calabi–Yau varieties of dimension nn. The construction gives minimal log discrepancies that decay doubly exponentially with dimension and are close to the conjecturally optimal values for pairs, providing evidence for the conjecture; the source does not state that it has been resolved.
