    LC reductions yield isomorphic simplicial complexes

  • Original language description

    We say that a vertex v of a finite simplicial complex K is LC-removable if the link of v is a cone, and that K is LC-irreducible if it has no LC-removable vertices. Answering a question of Civan and Yalcin, we prove that all LC-irreducible simplicial complexes that can be obtained from a given K by repeatedly deleting LC-removable vertices (plus all simplices containing them) are isomorphic.

    LC redukcemi vznikaji isomorfní simpliciální komplexy

  • Czech description

    Vrchol v simpliciálního komplexu K se nazývá LC-smazatelný, pokud jeho link je kužel, a K je LC=neredukovatelný, pokud nemá žádné LC-smazatelné vrcholy. Dokazuje se, že všechny LC-isomorfní komplexy, které mohou z daného K vzniknout odstraňováním LC-smazatelných vrcholů, jsou isomorfní, což odpovídá na otázku Civana and Yalcina.
