Asymptotics of the hypergraph bipartite Turán problem

Domagoj Bradač, Lior Gishboliner, Oliver Janzer +1

For positive integers $s, t, r$ , let $K_{s, t}^{(r)}$ denote the $r$ -uniform hypergraph whose vertex set is the union of pairwise disjoint sets $X, Y_{1}, \dots, Y_{t}$ , where $∣ X ∣ = s$ and…

The Turán number of the grid

Domagoj Bradač, Oliver Janzer, Benny Sudakov +1

For a positive integer $t$ , let $F_{t}$ denote the graph of the $t \times t$ grid. Motivated by a 50-year-old conjecture of Erdős about Turán numbers of $r$ -degenerate graphs, we prov…
