Chromatic Ramsey Numbers and Two‐Color Turán Densities
Journal of Graph Theory, EarlyView.ABSTRACT Given a graph G, its 2‐color Turán number ex ( 2 ) ( n , G ) is the maximum number of edges in an n‐vertex graph, such that the edges can be colored with two colors avoiding a monochromatic copy of G. Let π ( 2 ) ( G ) = lim n → ∞ ex ( 2 ) ( n , G ) / n 2 be the 2‐color Turán density of G.

Ramsey theory of the Henson graphs
, 2019 We use techniques of logic, particularly set theory, to determine upper bounds on the big Ramsey degrees of the universal homogeneous k-clique-free graphs, for each k greater than two.Non UBCUnreviewedAuthor affiliation: University of ...

On Policy Relevance of Ramsey Tax Rules [PDF]
, 2007 The Ramsey approach to optimal taxation and Ramsey tax rules have amassed substance in economic theory. However, they are often criticized on grounds of practicality, fairness, feasibility and some other aspects of designing actual tax policy. This paper

Topics in Gallai-Ramsey theory
, 2020 This book explores topics in Gallai-Ramsey theory, which looks into whether rainbow colored subgraphs or monochromatic subgraphs exist in a sufficiently large edge-colored complete graphs.

Tree Independence Number III. Thetas, Prisms and Stars
Journal of Graph Theory, EarlyView.ABSTRACT We prove that for every t ∈ N $t\in {\mathbb{N}}$ there exists τ = τ ( t ) ∈ N $\tau =\tau (t)\in {\mathbb{N}}$ such that every (theta, prism, K 1 , t ${K}_{1,t}$)‐free graph has tree independence number at most τ $\tau $ (where we allow “prisms” to have one path of length zero).

Finite Ramsey Theory through Category Theory
, 2022 We present a new, category theoretic point of view on finite Ramsey theory. Our aims are as follows: -- to define the category theoretic notions needed for the development of finite Ramsey Theory, -- to state, in terms of these notions, the general ...

Disparities in Hearing Screening Practices in Minnesota Elementary Schools
The Laryngoscope, EarlyView.ABSTRACT Objective Identifying and addressing pediatric hearing loss is critical to supporting a child's development. School‐based hearing screening is a mainstay of timely identification of hearing loss. The objectives of this study were to characterize the current hearing screening practices in public, charter, and private elementary schools in ...

Size multipartite Ramsey numbers for small paths versus books
Indonesian Journal of Combinatorics, 2016 Given $j \ge 2$, for graphs $G$ and $H$, the size Ramsey multipartite number $m_j(G, H)$ is defined as the smallest natural number $t$ such that any blue red coloring of the edges of the graph $K_{j \times t}$, necessarily containes a red $G$ or a ...
