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.

Mar1   comment   The semicat of morphisms which are neither right nor left invertibleJust a curiosity, how does a class of morphisms which are neither left nor right invertible be category? identities are always both right and left invertible.
Jan28  answered  In your opinion, what are the relative advantages of n-fold categories and n-categories?

Dec10  comment   Is there a high-concept explanation for why characteristic 2 is special?For the combinatorial point of view I guess that the importance of 2 is linked to the fact that for every set $X$ there's the canonical representation of each subset of $X$ with an element of $2^X$ which by the way is the support of a $F_2$ vector space, the space $\prod_{x \in X} \mathbb Z/2 \mathbb Z$. About other anomalies related to characteristic 2, I wonder if they are due to the fact that in characteristic 2 inverse coincide with identity and so we don't have the (involutive) symmetry respect to 0.
