Splitting necklaces, with constraints

D Jojic, G Panina, R Zivaljevic - SIAM Journal on Discrete Mathematics, 2021 - SIAM
We prove several versions of Alon's necklace-splitting theorem, subject to additional
constraints, as illustrated by the following results.(1) The “almost equicardinal necklace …

A Tverberg type theorem for collectively unavoidable complexes

D Jojić, G Panina, R Živaljević - Israel Journal of Mathematics, 2021 - Springer
We prove that the symmetrized deleted join SymmDelJoin (KK) of a “balanced family” KK=<
K i> i= 1 r of collectively r-unavoidable subcomplexes of 2 m is (m− r− 1)-connected. As a …

[PDF][PDF] Note on combinatorial structure of self-dual simplicial complexes

M Timotijevic - Mat. Vesnik, 2019 - vesnik.math.rs
Simplicial complexes K, in relation to their Alexander dual ̂K, can be classified as self-dual
(K= ̂K), sub-dual (K⊆ ̂K), super-dual (K⊇ ̂K), or transcendent (neither sub-dual nor …

Topology of unavoidable complexes

The partition number $\pi (K) $ of a simplicial complex $ K\subset 2^{[m]} $ is the minimum
integer $\nu $ such that for each partition $ A_1\uplus\ldots\uplus A_\nu=[m] $ of $[m] $ at …
