new-tag Two new tags distributive and lattices. Those tag names do not seem very good to me - I guess distributive-lattices would be better, if such tag is needed.

Q: Show that a distributive lattice can be embedded into product of two-element lattices

Tereza TizkovaI have seen this exercise in Bergman: Universal Algebra: Fundamentals and Selected Topics. Let $L$ be a distributive lattice and let $2$ be a 2-element lattice. Show that there is a set $J$ and lattice embedding $h: L \rightarrow 2^J$ such that for every $j \in J$, $\pi_j \circ h$ is surjective. ...

There is this old deleted post on meta about lattices: Tag merging and synonyms
> EDIT: Since there were several upvotes and no objections, two new tags lattice-orders and integer-lattices have already been created and now the question tagged lattices will be slowly retagged
> EDIT2: As you probably noticed, lattices is empty for some time already. (I thought it was good idea to make a note about this fact here as well.)
The post was deleted by a mod back in 2013: math.meta.stackexchange.com/posts/3187/revisions

Q: Reference for k-algebras in algebraic geometry

CornmanI am currently learning about algebraic geometry and k-algebras are mentioned without (clear) definition, so the basics are assumed in the lecture. I tried to look the topic up, but did not find a "pleasent" overview. In Lang's book he mentions modules, which I would try to avoid (if possible), a...
