Monochromatic sums and products
Discrete Analysis, 2016 Monochromatic sums and products, Discrete Analysis 2016:5, 48pp. An old and still unsolved problem in Ramsey theory asks whether if the positive integers are coloured with finitely many colours, then there are positive integers $x$ and $y$ such that $x,

FinTech and Environmental Sustainability: Evidence From Brazil
Sustainable Development, EarlyView.ABSTRACT This study explores the dynamic interplay between economic growth and environmental sustainability from a FinTech perspective, using Brazil as a case study. While FinTech's contribution to green transformation, sustainable finance, and resource efficiency has gained increasing attention, a notable lack of empirical research remains to assess ...

Temporal Ramsey Graphs: The Ramsey Kinematic Approach to the Motion of Systems of Material Points
DynamicsThe Ramsey approach is applied to analyses of the kinematics of systems built of non-relativistic, motile point masses/particles. This approach is based on colored graph theory. Point masses/particles serve as the vertices of the graph.

Ramsey-Theory and Forcing Extensions [PDF]
Proceedings of the American Mathematical Society, 1994 In every forcing extension of every model of set theory by a nontrivial (set) forcing there exist a graph Y and a cardinal μ \mu , such that every graph has an edge coloring with μ \mu . colors with no monochromatic induced copy of Y.

Energy Poverty and Climate Shocks: Are Changing Weather Patterns Leaving South Africa in the Dark?
Sustainable Development, EarlyView.ABSTRACT Energy and climate change are deeply interlinked, with the latter exerting significant influence on energy demand and supply. In regions such as South Africa, where socio‐economic vulnerability is high, understanding how climate change affects energy poverty is essential to achieving the Sustainable Development Goals, particularly SDG 7 ...

Riemannian Manifolds, Closed Geodesic Lines, Topology and Ramsey Theory
MathematicsWe applied the Ramsey analysis to the sets of points belonging to Riemannian manifolds. The points are connected with two kinds of lines: geodesic and non-geodesic.

Sustainable Development, EarlyView.ABSTRACT Identifying the principal drivers of carbon emissions is vital for designing effective mitigation strategies and supporting long‐term environmental sustainability. Although previous studies have explored multiple determinants of emissions, limited attention has been paid to the most influential energy–technology channels within trade‐dependent

History, EarlyView.Abstract In the summer of 1919, W. T. Goode, the Manchester Guardian’s special correspondent in Russia and the Baltic, was arrested in the Estonian capital Tallinn and briefly detained aboard a British warship. Goode's detention caused a furore, leading to accusations of kidnap, heated commentary in the press and questions in parliament.
