As a consequence we provide a positive answer to the problem … WebFor all «-manifolds M and N, the Disc Theorem shows that a diffeomorphism f: N -> N#H, extends to a diffeomorphism /#1: N#M -> (JV#2)#M. In fact, one has I(N) + I(M) C I(N#M). To show that inclusion is sometimes strict, D. Wilkens [18] constructed 15-manifolds M and N with I(M) - I(N) = 0 and I(M#N) = Z127. honey daily dose https://urbanhiphotels.com

WebSep 8, 2016 · An embedding is not "homotopy equivalent" to another embedding, this is reserved for spaces. And besides the standard embedding and Alexander's horned sphere's embedding are homotopic as maps S 2 → R 3, because R 3 is contractible anyway.
