Variety of commutative semi group
Judging from the result that you expect, I'm suspecting that you are after the variety of a commutative semigroup ring? Maybe one that satisfies $x_i^2 = x_i^3$ for each indeterminate $x_i$? Please rework this questions, at the moment it makes no sense. |

example of Local cohomology
Local cohomology vanishes for all $i < \text{depth}(M)$. Doesn't this give examples right away? |
