Blow-up trick in Combinatorics

Veronica Phan

Blow-up in graph theory is a procedure in which each vertex is replaced by copies of itself, and two copies are adjacent if and only if the original vertices are adjacent. In this…

A simple proof that the edge density of Fon-der-Flaass $(3, 4)$ -graph is $\geq \frac{7}{16} (1 - o (1))$

Veronica Phan

In 2018, Alexander A. Razborov proved that the edge density of Fon-der-Flaass $(3, 4)$ -graph is $\geq \frac{7}{16} (1 - o (1))$ , using flag algebras. In this paper, we give an elementary…

Entropy approach for a generalization of Frankl's conjecture

Veronica Phan

In this paper, we will use the entropy approach to derive a necessary and sufficient condition for the existence of an element that belongs to at least half of the sets in a finite…
