I'm math student, in particular I'm interested in algebra, geometry, topology and category theory (especially higher dimensional category theory) and its application in mathematics.

comment Do adjoint functors really define monads?
@student What should exactly be the action of $\mathfrak g$ on $M$? $M$ should be $\mathfrak g$ module or just a module?

@porton Since $i^{-1}(U')=\{x \in A \mid i(x)=x \in U'\}=U' \cap A=U$, so $f^{-1}(U')=(i \circ \bar f)^{-1}(U')=\bar f^{-1}(i^{-1}(U'))=\bar f^{-1}(U)$.

@porton My apologize, I've added some details I hope now I've made myself more clear. If that's not the case feel free to ask.:)
