comment Can one properly embed a differential manifold into numerical space of double dimension?
@Igor: Ryan Budney very concisely sketches a strategy for modifying Whitney's proof into one giving a proper embedding. Is there an actual proof in the literature ?

It is a bit harsh to downvote and vote for closing: Wesley has asked on MSE and has not received an answer that satisfies him. What is he supposed to do now?

comment Complex geometry text/research introduction for the analyst
Dear @Koushik, I think you should express yourself a bit more modestly when you criticize a book by a world-renowned specialist like Krantz. You are perfectly entitled not to like the book but you should give valid mathematical arguments, and not rudely dismiss it as "not a good book" and "quite horrible" without the shadow of an explanation.

comment What is the etymology of the term “perverse sheaf”?
What a cheap way to get reputation points: just invent a brilliant chunk of mathematics and 40 years later reap the benefits by remembering why you chose the terminology...
