On the Hardness of Switching to a Small Number of Edges
ABSTRACT Seidel's switching is a graph operation which makes a given vertex adjacent to precisely those vertices to which it was non‐adjacent before, while keeping the rest of the graph unchanged. Two graphs are called switching‐equivalent if one can be made isomorphic to the other one by a sequence of switches. Jelínková et al. [DMTCS 13, no. 2, 2011]

On the Local Resilience of Random Geometric Graphs With Respect to Connectivity and Long Cycles
ABSTRACT Given an increasing graph property 𝒫, a graph G$$ G $$ is α$$ \alpha $$‐resilient with respect to 𝒫 if, for every spanning subgraph H⊆G$$ H\subseteq G $$ where each vertex keeps more than a (1−α)$$ \left(1-\alpha \right) $$‐proportion of its neighbors, H$$ H $$ has property 𝒫.

Equivalence between Erdős–Hajnal and polynomial Rödl and Nikiforov conjectures
Abstract It is well‐known that polynomial versions of theorems of Rödl and Nikiforov, as conjectured by Fox and Sudakov and Nguyen, Scott and Seymour imply the classical Erdős–Hajnal conjecture. In this note, we prove that these three conjectures are in fact equivalent, extending several previous particular results in this direction by Fox, Nguyen ...

Generalized noncrossing partitions and combinatorics of Coxeter groups [PDF]
This thesis serves two purposes: it is a comprehensive introduction to the ``Catalan combinatorics'' of finite Coxeter groups, suitable for nonexperts, and it also introduces and studies a new generalization of the poset of noncrossing partitions.
