Amoeba Measures of Random Plane Curves

Ali Ulaş Özgür Kişisel, Jean-Yves Welschinger

We prove that the expected area of the amoeba of a complex plane curve of degree is less than and once rescaled by , is asympto…

Morse shellings out of discrete Morse functions

Jean-Yves Welschinger

From the topological viewpoint, Morse shellings of finite simplicial complexes are {\it pinched} handle decompositions and extend the classical shellings. We prove that every discr…

Shellable tilings on relative simplicial complexes and their h-vectors

Jean-Yves Welschinger

An h-tiling on a finite simplicial complex is a partition of its geometric realization by maximal simplices deprived of several codimension one faces together with possibly their r…

Spectral sequences of a Morse shelling

Jean-Yves Welschinger

We recently introduced a notion of tilings of geometric realizations of finite relative simplicial complexes and related those tilings to the discrete Morse theory of R. Forman, es…

Morse shellings on products

Jean-Yves Welschinger

We recently defined a property of Morse shellability (and tileability) of finite simplicial complexes which extends the classical one and its relations with discrete Morse theory.…

Morse shellings and compatible discrete Morse functions

Nermin Salepci, Jean-Yves Welschinger

We introduce a notion of Morse shellings (and tilings) on finite simplicial complexes which extends the classical one and its relation to discrete Morse theory.Skeletons and baryce…
