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 Proof completion: if $Y$ is a closed term in strong nf, then $Yx$ weakly reduces to a strong nf $Z$
@RoyO. I'm probably a little rusty, but isn't it true that a reduction of a term has complexity less than the starting term?

@DanaeKissinger Ok, then I think my answer said something about that too, let me edit a little bit to make it clear.

Anyway if you have more question I suppose it's better to go in chat :)

Definitions are the rules for the type.

comment How do definitions work in Martin-Lof type theory?
@user18921 Definition of inductive type in a type theory works like the definition of any other type: you state a rule for the introduction of the type (one that state that the constant of language that represent the type is indeed a type) and some constructors, eliminators and computational rules. The only difference is that such rules are required to have a certain format.

comment Types, Sets and Categories
@CristianGarcia $C_0$ is the type, so of course they have all the same type :), at least this is the usual type theoretic definition of category.

comment Using types instead for basic proofs
@ChristianGarcia Are you trying to consider membership as a relations in the proposition as type paradigm?
