Minimal disc diagrams of 5/9-simplicial complexes
Ioana-Claudia Lazar
We introduce and study a local combinatorial condition, called the 5/9-condition, on a simplicial complex, implying Gromov hyperbolicity of its universal cover. We hereby give an a…
The collapsibility of some CAT(0) simplicial complexes of dimension 3
Ioana-Claudia Lazar
We study the collapsibility of finite simplicial complexes of dimension 3 endowed with a CAT(0) metric. Our main result states that, under an additional hypothesis, finite simplici…
A combinatorial negative curvature condition implying Gromov hyperbolicity
Ioana-Claudia Lazar
We explore a local combinatorial condition on a simplicial complex, called 8-location. We show that 8-location and simple connectivity imply Gromov hyperbolicity. We mention some a…
A note on the combinatorial structure of finite and locally finite simplicial complexes of nonpositive curvature
Djordje Baralic, Ioana-Claudia Lazar
We investigate the collapsibility of systolic finite simplicial complexes of arbitrary dimension. The main tool we use in the proof is discrete Morse theory. We shall consider a co…
