I think that differential-topology is an appropriate tag

Jul 2, 2013 at 9:57 comment added user81500 Thank you for your answer. I am thinking about smooth embeddings......
Jul 1, 2013 at 19:13 comment added Serge Lvovski @Neil. The algebraic version is pretty easy: if dimension of the ambient Grassmannian is at least four, then no such embedding exists. Indeed, Picard group of any Grassmannian is $\mathbb Z$, so each divisor is ample, so Picard of each codimension one smooth subvariety is also $\mathbb Z$.
Jul 1, 2013 at 17:29 comment added Neil Strickland Are you thinking about algebraic embeddings (as suggested by quid's tags) or about smooth or topological embeddings? I suspect that all three versions are quite hard, but the algebraic version should be easier than the other two.
Jul 1, 2013 at 17:24 comment added user9072 Welcome to MO! I added the tag ag.algebraic-geometry; it is costumary to always use at least one of the top-level tags, those with a two-letter prefix corresponding to arXiv categeroies. I hope I picked the right one, you can always change this via using the link edit below the question.
