A Time-Fractional Differential Inequality of Sobolev Type on an Annulus
Axioms, 2023 Several phenomena from natural sciences can be described by partial differential equations of Sobolev-type. On the other hand, it was shown that in many cases, the use of fractional derivatives provides a more realistic model than the use of standard ...

Nonexistence results of solutions for some fractional $p$-Laplacian equations in $\mathbb{R}^{N}$
Electronic Journal of Qualitative Theory of Differential EquationsIn the present paper, we study the nonexistence of nontrivial weak solutions to a class of fractional $p$-Laplacian equation in two cases which are $sp > N$ and $sp < N$.

Business Strategy and the Environment, EarlyView.ABSTRACT The present study applied the diffusion of innovation theory to investigate the rate of diffusion of renewable energy sources used by Europe's top professional football stadiums and the relationship with carbon neutrality. A discrete diffusion model estimated the diffusion of renewable energy to saturation, and a multivariate logistic ...

Greening the Bottom Line: Public Funding for Circular Economy Initiatives and Financial Stability
Business Strategy and the Environment, EarlyView.ABSTRACT Public funding for circular economy (CE) initiatives plays a crucial role in shaping corporate financial performance, yet its effects remain underexplored. Grounded in the resource‐based view (RBV) of the firm, this study investigates the financial impact of CE funding on private firms, using Portugal as a case study. It analyses the financial
