Rainbow Turán problems for forbidden subposets
Balázs Patkós
A family of sets is a copy of a poset if is isomorphic to . The forbidden subposet problem asks for determini…
Turán problems for simplicial complexes
Maria Axenovich, Dániel Gerbner, Dingyuan Liu +1
An abstract simplicial complex is a non-uniform hypergraph without isolated vertices, whose edge set is closed under taking subsets. The extremal number $\mathrm{ex}(n…
Poset saturation of unions of chains
Shengjin Ji, Balázs Patkós, Erfei Yue
A family of sets is a(n induced) copy of a poset if there exists a bijection such that holds if and only…
Bipartite Turán number of trees
Yair Caro, Balázs Patkós, Zsolt Tuza
We start a systematic investigation concerning bipartite Turán number for trees. For a graph and integers we define: \quad is the largest…
Size, diversity, minimum degree, sturdiness, dömdödöm
Balázs Patkós
For a family of sets and a disjoint pair we let . The \textbf{-dömdöd…
Identification of a monotone Boolean function with "reasons" as a combinatorial search problem
Dániel Gerbner, András Imolay, Gyula O. H. Katona +5
We study the number of queries needed to identify a monotone Boolean function . A query consists of a 0-1-sequence, and the answer is the value of…
