Why Realisms about Fiction Must (and Can) Accommodate Fictional Properties
The topic of fictional objects is a familiar one, the topic of fictional properties less so. But it deserves its own place in the philosophy of fiction, if only because fictional properties have such a prominent role to play in science fiction and ...

Abstract The integrity of scholarly communication depends critically on the accuracy and verifiability of cited references. Citations enable readers to trace prior work, assess evidence, and situate new contributions within the existing literature. However, concerns have emerged regarding the presence of references in published papers that cannot be ...

Nonexistence of positive solutions for a nonpositone system in a ball
In this article, we prove the nonexistence of positive solutions for a nonpositone system in a ball when the nonlinearities may have more than one zero.

Nonexistence of global solutions of abstract wave equations with high energies
We consider an undamped second order in time evolution equation. For any positive value of the initial energy, we give sufficient conditions to conclude nonexistence of global solutions. The analysis is based on a differential inequality.

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 ...

On the critical behavior for a Sobolev-type inequality with Hardy potential
We investigate the existence and nonexistence of weak solutions to the Sobolev-type inequality $ -\partial _t(\Delta u)-\Delta u+ \frac{\sigma }{|x|^2}u \ge |x|^{\mu }|u|^p$ in $(0,\infty )\times B$, under the inhomogeneous Dirichlet-type boundary ...

The nonexistence of regularization operators
With references to applications in physics the author discusses the well known problem of regularization of generalized functions. As is known, there exist various procedures to regularize some concrete classes of generalized functions. For generalized functions on the real line the author shows that there cannot exist a unique procedure which provides

Nonexistence of Graphs with Cyclic Defect [PDF]
In this note we consider graphs of maximum degree $\Delta$, diameter $D$ and order ${\rm M}(\Delta,D) - 2$, where ${\rm M}(\Delta,D)$ is the Moore bound, that is, graphs of defect 2. Delorme and Pineda-Villavicencio conjectured that such graphs do not exist for $D\geq 3$ if they have the so called 'cyclic defect'.

Greening the Bottom Line: Public Funding for Circular Economy Initiatives and Financial Stability
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
