The Turán Density of 4-Uniform Tight Cycles

Maya Sankar

For any uniformity $r$ and residue $k$ modulo $r$ , we give an exact characterization of the $r$ -uniform hypergraphs that homomorphically avoid tight cycles of length $k$ modulo $r$ …

An Improved Turán Exponent for 2-Complexes

Maya Sankar

The topological Turán number $ex_{h o m} (n, X)$ of a 2-dimensional simplicial complex $X$ asks for the maximum number of edges in an $n$ -vertex 3-uniform hypergraph containi…

Generalized Ramsey--Turán density for cliques

Jun Gao, Suyun Jiang, Hong Liu +1

We study the generalized Ramsey--Turán function $RT (n, K_{s}, K_{t}, o (n))$ , which is the maximum possible number of copies of $K_{s}$ in an $n$ -vertex $K_{t}$ -free graph with indepe…
