| Dec 12, 2023 at 22:11 | comment | added | Marco Golla | Sorry, just to make sure I understand the notation: the lattice is of rank 3, and it's a hyperbolic summand (-xz) plus a diagonal one? It looks very much non-unimodular to me, and also it looks like it's only a half-integral lattice. Do you mean to have a 2 in front of -yz? (I'm not familiar with the Mukai pairing on K3s.) | |
