Shellable tilings on simplicial complexes
Jean-Yves Welschinger (Institut Camille Jordan, Université Lyon 1)
Abstract: I will introduce a notion of shellable tilings on finite simplicial complexes, prove their existence after finitely many stellar subdivisions and discuss their relations with discrete Morse theory and h-vectors. Every shelled tiling computes the (co)homology of the complex via two spectral sequences. As a consequence, I deduce the existence of piecewise-linear pinched handle decompositions for all closed triangulated manifolds.
