Special Issue Information

Dear Colleagues,

In recent years, the investigation with fractional calculus has broken into the field of mathematical analysis, both at the theoretical level and at the level of its applications. Fractional calculus has become an important tool for modeling analysis and has played a very important role in various fields, such as fluid mechanics, viscoelasticity, physics, biology, chemistry, dynamical systems, signal processing or entropy theory. There are many definitions of fractional integrals and derivatives in the literature, and many important inequalities have been obtained for these definitions. On the other hand, the concept of symmetry is a beauty structure used to describe the environment and problems of the real world, as well as to strengthen the relationship between mathematical science and applied science such as physics and engineering. Therefore, the concept of symmetry exists in fractional calculus as in many other fields. In this special issue, the concept of Symmetry will be in the foreground.

The purpose of this Special Issue is to publish original and high-quality papers covering the latest advances in the theory of Fractional calculus with symmetry as well as generalizations of fractional important inequalities.

The issue of the subject will be focused but not limited to:

  • Fractional integral inequalities;
  • Symmetry in fractional operators and models;
  • q-inequalities via fractional calculus;
  • Fractional differential equations and inclusions;
  • Symmetry on fractal and fractional differential operators;
  • Discrete fractional equations;
  • Fractional Calculus- new fractional definitions, their properties and applications;
  • Fractional (p, q)-calculus

Abstract
This article discusses several forms of Ulam stability of nonlinear fractional delay differential equations. Our investigation is based on a generalised Gronwall’s inequality and Picard operator theory. Implementations are provided to demonstrate the stability results obtained for finite intervals.

Then, a Newton-type inequality via partially differentiable coordinated convex mappings is derived by taking the absolute value of the obtained identity.

In this paper, firstly, we present an integral identity for functions of two variables via Riemann–Liouville fractional integrals. Then, a Newton-type inequality via partially differentiable coordinated convex mappings is derived by taking the absolute value of the obtained identity. Moreover, several inequalities are obtained with the aid of the Hölder and power mean inequality. In addition, we investigate some Newton-type inequalities utilizing mappings of two variables with bounded variation. Finally, we gave some mathematical examples and their graphical behavior to validate the obtained inequalities. Full article

This work aims at a new semi-analytical method called the variational iteration transformation method for solving nonlinear homogeneous and nonhomogeneous fractional-order gas dynamics equations. The Shehu transformation and the iterative technique are applied to solve the suggested problems. The proposed method has an advantage over existing approaches because it does not require additional materials or computations. Four problems are used to test the authenticity of the proposed method. Using the suggested method, the solution proves to be more accurate. The proposed method can be implemented to solve many nonlinear fractional order problems because it has a straightforward implementation. Full article

Many scholars have recently become interested in establishing integral inequalities using various known fractional operators. Fractional calculus has grown in popularity as a result of its capacity to quickly solve real-world problems. First, we establish new fractional inequalities of the Hadamard–Mercer, Pachpatte–Mercer, and Dragomir–Agarwal–Mercer types containing an exponential kernel. In this regard, the inequality proved by Jensen and Mercer plays a major role in our main results. Integral inequalities involving convexity have a wide range of applications in several domains of mathematics where symmetry is important. Both convexity and symmetry are closely linked with each other; when working on one of the topics, you can apply what you have learned to the other. We consider a new identity for differentiable mappings and present its companion bound for the Dragomir–Agarwal–Mercer type inequality employing a convex function. Applications involving matrices are presented. Finally, we conclude our article and discuss its future scope. Full article
