One of the major problems in combinatorics is to determine the number of $r$-uniform hypergraphs ($r$-graphs) on $n$ vertices which are free of certain forbidden structures. This problem dates back to the work of Erd\H{o}s, Kleitman and Rothschild, w

A graph where each vertex $v$ has a list $L(v)$ of available colors is $L$-colorable if there is a proper coloring such that the color of $v$ is in $L(v)$ for each $v$. A graph is $k$-choosable if every assignment $L$ of at least $k$ colors to each v

The Erd\H{o}s-Simonovits stability theorem states that for all \epsilon >0 there exists \alpha >0 such that if G is a K_{r+1}-free graph on n vertices with e(G) > ex(n,K_{r+1}) - \alpha n^2, then one can remove \epsilon n^2 edges from G to obtain an

An ordered graph is a simple graph with an ordering on its vertices. Define the ordered path P n to be the monotone increasing path with n edges. The ordered size Ramsey number r ( P r , P s ) is the minimum number m for which there exists an ordered
A triangle $T'$ is $\varepsilon$-similar to another triangle $T$ if their angles pairwise differ by at most $\varepsilon$. Given a triangle $T$, $\varepsilon>0$ and $n\in\mathbb{N}$, B\'ar\'any and F\"uredi asked to determine the maximum number of tr

A well-known conjecture by Erdős states that every triangle-free graph on n vertices can be made bipartite by removing at most \(n^2/25\) edges. This conjecture was known for graphs with edge density at least 0.4 and edge density at most 0.172. Here

The Erdős–Szekeres Theorem stated in terms of graphs says that any red–blue coloring of the edges of the ordered complete graph K r s + 1 contains a red copy of the monotone increasing path with r edges or a blue copy of the monotone increasing
