[HTML][HTML] On the exact maximum induced density of almost all graphs and their inducibility

R Yuster - Journal of Combinatorial Theory, Series B, 2019 - Elsevier
Let H be a graph on h vertices. The number of induced copies of H in a graph G is denoted
by i H (G). Let i H (n) denote the maximum of i H (G) taken over all graphs G with n vertices …

Anticoncentration for subgraph statistics

M Kwan, B Sudakov, T Tran - Journal of the London …, 2019 - Wiley Online Library
Consider integers k, ℓ such that 0⩽ ℓ⩽ k 2. Given a large graph G, what is the fraction of k‐
vertex subsets of G which span exactly ℓ edges? When G is empty or complete, and ℓ is zero …

[HTML][HTML] Strong forms of stability from flag algebra calculations

O Pikhurko, J Sliačan, K Tyros - Journal of Combinatorial Theory, Series B, 2019 - Elsevier
Given a hereditary family G of admissible graphs and a function λ (G) that linearly depends
on the statistics of order-κ subgraphs in a graph G, we consider the extremal problem of …

Combinatorial anti-concentration inequalities, with applications

J Fox, M Kwan, L Sauermann - Mathematical Proceedings of the …, 2021 - cambridge.org
We prove several different anti-concentration inequalities for functions of independent
Bernoulli-distributed random variables. First, motivated by a conjecture of Alon, Hefetz …

Inducibility of directed paths

I Choi, B Lidický, F Pfender - Discrete Mathematics, 2020 - Elsevier
A long standing open problem in extremal graph theory is to describe all graphs that
maximize the number of induced copies of a path on four vertices. The character of the …

Edge-statistics on large graphs

N Alon, D Hefetz, M Krivelevich… - … Probability and Computing, 2020 - cambridge.org
The inducibility of a graph H measures the maximum number of induced copies of H a large
graph G can have. Generalizing this notion, we study how many induced subgraphs of fixed …

Stability from graph symmetrisation arguments with applications to inducibility

H Liu, O Pikhurko, M Sharifzadeh… - Journal of the London …, 2023 - Wiley Online Library
We present a sufficient condition for the stability property of extremal graph problems that
can be solved via Zykov's symmetrisation. Our criterion is stated in terms of an analytic limit …

[HTML][HTML] On the inducibility of cycles

D Hefetz, M Tyomkyn - Journal of Combinatorial Theory, Series B, 2018 - Elsevier
Abstract In 1975 Pippenger and Golumbic proved that any graph on n vertices admits at
most 2 e (n/k) k induced k-cycles. This bound is larger by a multiplicative factor of 2e than the …

On the maximum number of odd cycles in graphs without smaller odd cycles

A Grzesik, B Kielak - Journal of Graph Theory, 2022 - Wiley Online Library
We prove that for each odd integer k≥ 7, every graph on n vertices without odd cycles of
length less than k contains at most (n∕ k) k cycles of length k. This extends the previous …
