Special Issue Information

Dear Colleagues,

The study of fractional differential equations, which involve derivatives and integrals of non-integer orders, has gained significant momentum in recent years due to their ability to model complex phenomena with memory and hereditary properties. These equations provide a more accurate and flexible framework for describing processes in a wide range of disciplines, including physics, biology, engineering, finance, and materials science.

This Special Issue aims to bring together cutting-edge research in the theory, analysis, numerical methods, and applications of fractional differential equations. We are particularly interested in innovative methodologies and modelling strategies that demonstrate the power of fractional calculus in capturing the dynamics of real-world systems, as well as interdisciplinary studies where fractional models provide new insights or improved results.

We welcome original research articles and review papers that address, but are not limited to, the following topics:

  • Theoretical advances in fractional differential equations;
  • Analytical and numerical methods for solving fractional-order models;
  • Stability, control, and bifurcation analysis of fractional dynamical systems;
  • Applications of fractional models in physics, engineering, biology, and other sciences;
  • Fractional order modelling in fluid mechanics;
  • Fractional-order modelling of viscoelastic, diffusive, and memory-dependent systems;
  • Fractional order models in epidemiology;
  • Computational techniques and software tools for fractional systems;
  • Comparisons of classical and fractional modelling approaches.

We look forward to receiving contributions that will foster progress in this vibrant and interdisciplinary field.

In this study, we introduce two new classes of contractions, namely enriched (I,ρ,χ)-contractions and generalized enriched (I,ρ,χ)-contractions, within the context of normed spaces. These classes generalize several well-known contraction types, including χ-contractions, Banach contractions, enriched contractions, Kannan contractions, Bianchini contractions, Zamfirescu contractions, non-expansive mappings, and (ρ,χ)-enriched contractions. We establish related fixed point results for the novel contractions in normed spaces endowed with the binary relations preserving key symmetric properties, ensuring consistency and applicability. The Krasnoselskij iteration method is refined to incorporate symmetric constraints, facilitating fixed point identification within these spaces. By appropriately selecting constants in the definition of enriched (I,ρ,χ)-contractions, employing a suitable binary relation, or control function χΘ, our framework generalizes and extends classical fixed point theorems. Illustrative examples highlight the significance of our findings in reinforcing fixed point conditions and demonstrating their broader applicability. Additionally, this paper explores how these ideas guarantee the stability of the production–consumption markets equilibrium and the economic growth model. Full article
