Derived subdivisions make every PL sphere polytopal.

Ivan Izmestiev, Karim Adiprasito— 2013

Focus Area 2: Delaunay Geometry We give a simple proof that some iterated derived subdivision of every PL sphere is combinatorially equivalent to the boundary of a simplicial polytope, thereby resolving a problem of Billera (personal communication).
