Sustainable Development, EarlyView.ABSTRACT This study explores the dynamic influence of income inequality on environmental quality in Malaysia and offers evidence‐based recommendations for climate action and policy. Using annual data from 1990 to 2022, the analysis utilizes the Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) framework combined with ...

Around a conjecture of Erdos in graph Ramsey theory
پژوهشهای ریاضی, 2021 For given graphs G1 and G2 the Ramsey number R(G1;G2), is the smallest positive integer n such that each blue-red edge coloring of the complete graph Kn contains a blue copy of G1 or a red copy of G2. In 1983, Erd}os conjectured that there is an absolute

Tracking SDG‐7 in China, India, and Japan
Sustainable Development, EarlyView.ABSTRACT This study examines the impact of clean energy consumption on environmental quality, supporting the UN Sustainable Development Goal (SDG) 7, which aims to ensure access to clean, affordable energy for all. The Auto‐Regressive Distributed Lag (ARDL) model is used for Japan, and the Fourier ARDL for China and India, followed by a Granger ...

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.

Discrete Mathematics, 1978 AbstractA graph G is totally connected if both G and Ḡ (its complement) are connected. The connected Ramsey number rc(F, H) is the smallest integer k ⩾ 4 so that if G is a totally connected graph of order k then either F ⊂ G or H ⊂ Ḡ. We show that if neither of F nor H contains a bridge, then rc = r(F, H), the usual generalized Ramsey number of F and H.

Sustainable Development, EarlyView.ABSTRACT Understanding whether the interaction between economic activity and forest ecosystems manifests as conflict or synergy is central to designing effective, sustainable development policies. Although the environmental Kuznets curve framework is frequently utilized to explain this relationship, its analytical scope remains limited, as it ...

Sustainable Development, EarlyView.ABSTRACT Water sustainability has become a critical challenge within the sustainable development agenda, particularly under increasing climate risks and resource pressures. Despite its central role in Sustainable Development Goal 6 (SDG 6), existing studies largely adopt fragmented and linear approaches, overlooking the interconnected and nonlinear ...

, 2005 Sequences Bn(p,q) of connected parts of Euclidean and hyperbolic (p,q)-mosaic graphs are considered. The smallest n such that any 2-coloring of the edges of Bn( p,q) contains a given monochromatic graph G is introduced as gameboard Ramsey number rp,q(G). For p ≥ 4 it is proved that these Ramsey numbers exist for finitely many graphs only.
