Pair of pants decomposition of 4–manifolds
Pair of pants decomposition of 4–manifolds
Using tropical geometry, Mikhalkin has proved that every smooth complex hypersurface in CP nC1 decomposes into pairs of pants: a pair of pants is a real compact 2nmanifold with cornered boundary obtained by removing an open regular neighborhood of n C 2 generic complex hyperplanes from CP n .As is …
