On certain equations and inequalities involving the arithmetical functions φ(n) and d(n)
Notes on Number Theory and Discrete Mathematics, 2022 By using the results and methods of [1], we will study the equation \varphi(n) + d(n) = \frac{n}{2} and the related inequalities. The equation \varphi(n) + d^2(n)=2n will be solved, too.

Regional Sustainability Assessment Under Risk and Uncertainty: A Water–Energy–Food Based Framework
Sustainable Development, EarlyView.ABSTRACT Regional sustainability assessment requires integrated structures that can examine the interactions between Water–Energy–Food (WEF) systems, socio‐economic risk conditions, and performance outcomes under uncertainty. This study proposes a multidimensional framework that combines a suitability index, composite sustainability indicators ...

Quasi-arithmetic Means Inequalities Criteria for Differentiable Functions
Journal of Mathematics Research, 2015 Quasi-arithmetic means are defined for continuous, strictly monotone functions. In the case that functions are twice differentiable, we obtained criteria for inequalities between finite number of quasi-arithmetic means in additional and multiplicative case. Applications for H\"older and Minkowski type inequalities are given.

Sustainable Development, EarlyView.ABSTRACT In 2015, the United Nations (UN) adopted the 17 Sustainable Development Goals (SDGs), calling for urgent action to end poverty, reduce inequality, and secure a sustainable future. Within this global agenda, the commitment of the Organization for Economic Co‐operation and Development (OECD) is particularly significant given its institutional ...

Sustainable Development, EarlyView.ABSTRACT This study examines the socioeconomic determinants of agricultural CO2 emissions in the 10 highest‐emitting agricultural economies from 1992 to 2022. Using the LM bootstrap cointegration method and the method of moments quantile regression (MMQR), the analysis identifies long‐run relationships and heterogeneous effects across the emissions ...

Sustainable Development Goals (SDGs) in European Countries: An Analytical and Econometric Approach
Sustainable Development, EarlyView.ABSTRACT Despite the growing policy relevance of the Sustainable Development Goals (SDGs) within the European Union, significant uncertainties remain regarding the extent to which European countries perform unevenly across different dimensions of sustainable development and whether higher levels of economic development necessarily translate into better

Some integral inequalities for operator arithmetic-geometrically convex functions
, 2015 In this paper, we introduce the concept of operator arithmetic-geometrically convex functions for positive linear operators and prove some Hermite-Hadamard type inequalities for these functions. As applications, we obtain trace inequalities for operators which give some refinements of previous results.

Sustainable Development, EarlyView.ABSTRACT The transition toward circular and sustainable growth remains a major challenge in Sub‐Saharan Africa (SSA), where resource constraints, limited recycling capacity, and infrastructure deficits constrain environmental performance. Drawing on circular economy and innovation systems perspectives, this study examines how financial technology ...
