| Aug 21, 2020 at 21:40 | comment | added | Greg Friedman | I'm not completely sure I understand how you're defining signatures with twisted coefficients. The way I usually see such things involves some sort of self-dual sheaf of coefficients. Can you say more about the definition of your twisted intersection form? | |
