I'm currently a PhD student in theuniversity of Geneva. For the moment, I work mainly in algebraic topology.

Displaying [ ], |, etc. in a TikZ matrix node Thank you percusse, this worked (and I feel like an idiot, but that's not a problem). Do you want to make an answer out of that, or should I make it ? |

How much connection is there between Commutative Algebra and Algebraic Topology? And for a slightly less cheap example, the cohomology of the total space of a fiber bundle is a module over the cohomology of the base space. |

orthogonal projection - simple exalanation needed To make this example even more concrete, let $D$ be $\mathbb{R}^2=\{(x,y)\}$ and $D'=\{(x,y)\in\mathbb{R}^2|y=0\}$. Now the orthogonal projection of $D$ on $D'$ is the map that sends any pair $(x,y)$ to the pair $(x,0)$. |

Surjective graded homomorphism of rings also an isomorphism? This doesn't work : the natural projection homomorphism is not a graded morphism (e.g. $t^{k+1} \mapsto t$ lowers the degree by $k$. |
