Jul 14, 2013 at 17:36 comment added Theo Johnson-Freyd Hi @Sepideh: These are good questions, but not really "research level". I recommend asking them on math.stackexchange, where there are many experts and the scope of the site is defined more broadly.

Jul 14, 2013 at 8:46 comment added Ryan Budney Q1: You are taking the union of two manifolds, and their common boundary is this product of spheres. This notation is indicating that you're gluing the manifolds together along this product of spheres. Q2: the boundary includes into the manifold, so there's a map of homotopy groups, and he's saying after you've formed this manifold, a particular sphere becomes trivial, since it bounds a disc.
