Weakened Gallai-Ramsey numbers [PDF]
Surveys in Mathematics and its Applications, 2018 In the Ramsey theory of graphs, one seeks to determine the value of the Ramsey number rt(n), defined to be the least natural number p such that every coloring of the edges of Kp using t colors results in a monochromatic copy of Kn in some color.

Using the Incompressibility Method to obtain Local Lemma results for Ramsey-type Problems
, 2008 We reveal a connection between the incompressibility method and the Lovasz local lemma in the context of Ramsey theory. We obtain bounds by repeatedly encoding objects of interest and thereby compressing strings. The method is demonstrated on the example

Biological Reviews, EarlyView.ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

, 2021 Ramsey theory is a field of mathematics dating back to approximately 100 years. It intersects with various branches of mathematics, such as combinatorics, number theory, geometry, topology and set theory [16]. Loosely speaking, Ramsey theory can be described as the study of structure which is preserved under partitions – an idea succinctly captured by ...

Sentience in cephalopod molluscs: an updated assessment
Biological Reviews, EarlyView.ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

MONOID ACTIONS AND ULTRAFILTER METHODS IN RAMSEY THEORY
Forum of Mathematics, Sigma, 2019 First, we prove a theorem on dynamics of actions of monoids by endomorphisms of semigroups. Second, we introduce algebraic structures suitable for formalizing infinitary Ramsey statements and prove a theorem that such statements are implied by the ...

Turán and Ramsey problems for alternating multilinear maps
Discrete Analysis, 2023 Turán and Ramsey problems for alternating multilinear maps, Discrete Analysis 2023:12, 22 pp. Ramsey's theorem (in its finite version) states that for every positive integer $k$ there exists a positive integer $n$ such that every graph with $n$ vertices

European Ports as Energy Hubs: A Sustainability Index to Assess Territorial Development
Business Strategy and the Environment, EarlyView.ABSTRACT The capacity of ports to act as energy hubs is increasingly relevant in light of sustainability challenges and global crises like the Ukraine conflict, the COVID‐19 pandemic and energy scarcity. Numerous international and national initiatives are shaping the future of port development to address environmental and economic concerns.
