For Weil divisors, even that might be out of reach. For an explicit example, see Example 11.4.6 in Fulton's Intersection Theory. | |
| May 30, 2017 at 19:08 | comment | added | Sándor Kovács | You essentially already answered your questions 1 and 2. For 3: if X is smooth, every Weil divisor is Cartier. If it isn't, then restriction doesn't always work. | |
