Agroecology and Transformative Adaptation to Climate Change
Asia Pacific Viewpoint, EarlyView.ABSTRACT This paper examines transformative adaptation to climate change through the EFICAS Project (Eco‐Friendly Intensification and Climate‐resilient Agricultural Systems) implemented across 12 upland communities in northern Laos from 2014 to 2020.

A NOTE ON BIGAUSSIAN PELL AND PELL-LUCAS NUMBERS
Journal of Science and Arts, 2021 In this study, we define a new type of Pell and Pell-Lucas numbers which are called biGaussian Pell and biGaussian Pell-Lucas numbers. We also give the relationship between negabiGaussian Pell and Pell-Lucas numbers and bicomplex Pell and Pell-Lucas numbers.

From Loss to Transformation? Towards Pluralistic and Politicised Agrarian‐Climate Futures
Asia Pacific Viewpoint, EarlyView.ABSTRACT Understanding how actors perceive and anticipate future states of the world is gaining traction in climate change governance scholarship and related calls for sustainability transformations. However, smallholder farmers, indigenous groups, and local communities, who are expected to bear disproportionate burdens of loss and damage from climate ...

GENERALIZATION OF PELL SEQUENCE AND PELL-LUCAS SEQUENCE, NEW RESULTS AND CIRCULANT MATRICES ASPECTS [PDF]
Some generalizations of Pell sequence and Pell-Lucas sequence, namely, (k,h)-Pell sequence and (k,h)-Pell-Lucas sequence are considered in this paper. We obtain generating functions, some identities and formulas for the sums of a finite number of terms ...

A STUDY ON PELL EQUATION [PDF]
, 2020 Pell equation (alternatively called the Pell- Fermat equation) is a type of a Diophantine equation of the form 2 -Dye 2 =1 for a natural number D. If D is a perfect square, then pell equation can be rewritten as y).(x+√y) = 1.similarly, the trivial ...

Three Diophantine equations concerning the polygonal numbers [PDF]
Notes on Number Theory and Discrete MathematicsMany authors investigated the problem about the linear combination of two polygonal numbers being a perfect square, i.e., the Diophantine equation mPₖ(x)+nPₖ(y)=z², where Pₖ(x) denotes the x-th k-polygonal number and m, n are positive integers.

Dual-Gaussian Pell and Pell-Lucas numbers
Cumhuriyet Science Journal, 2022 In this study, we define a new type of Pell and Pell-Lucas numbers which are called dual-Gaussian Pell and dual-Gaussian Pell-Lucas numbers. We also give the relationship between negadual-Gaussian Pell and Pell-Lucas numbers and dual-complex Pell and Pell-Lucas numbers.

Asia Pacific Viewpoint, EarlyView.ABSTRACT Contemporary rural change in Southeast Asia is shaped by complex, intersecting forces that defy simplistic narratives. Researchers must therefore develop new ways to grasp nuanced, non‐linear, and locally specific processes to understand how transformational shifts may occur (or not) in the region.

Equations with arithmetic functions of Pell numbers [PDF]
, 2014 Here, we prove some diophantine results about the Euler function of Pell numbers and their Pell-Lucas companion sequence. For example, if the Euler function of the nth Pell number Pn or Pell- Lucas companion number Qn is a power of 2, then n is greater ...
