Electric and magnetic fields of fractal distribution of charged particles are considered. The fractional integrals are used to describe fractal distribution. The fractional integrals are considered as approximations of integrals on fractals. Using the fractional generalization of integral Maxwell equation, the simple examples of the fields of homogeneous fractal distribution are considered. The...

where D , D , and D are the standard Riemann-Liouville fractional derivatives, I and I are the Riemann-Liouville fractional integrals, and 0 < γ < 1 < β < 2 < α < 3, ν,ω > 0, 0 < η, ξ < 1, k ∈R, f ∈ C([0, 1]×R×R,R), g ∈ C([0, 1]×R,R). The p-Laplacian operator is defined as φp(t) = |t|p–2t, p > 1, and (φp) = φq, 1 p + 1 q = 1. The study of boundary value problems in the setting of fractional cal...

*Correspondence: [email protected] Department of Mathematics and Physical Sciences, Prince Sultan University, P.O. Box 66833, Riyadh, 11586, Saudi Arabia Abstract In this article, we extend fractional calculus with nonsingular exponential kernels, initiated recently by Caputo and Fabrizio, to higher order. The extension is given to both left and right fractional derivatives and integrals. ...

The problems of unique solvability initial for linear inhomogeneous equations a general form with several Gerasimov-Caputo fractional derivatives in Banach spaces are investigated. Cauchy problem is considered an equation solved respect to the highest derivative containing bounded operators at lowest derivatives. solution presented use Dunford-Taylor type integrals. obtained result allowed us s...

In this paper, we first consider the general fractional derivatives of arbitrary order defined in Riemann–Liouville sense. particular, deduce an explicit form their null space and prove second fundamental theorem calculus that leads to a closed formula for projector operator. These results allow us formulate natural initial conditions differential equations with part develop operational Mikusi?...

In this article, we survey the asymptotic stability analysis of fractional differential systems with the Prabhakar fractional derivatives. We present the stability regions for these types of fractional differential systems. A brief comparison with the stability aspects of fractional differential systems in the sense of Riemann-Liouville fractional derivatives is also given.

We consider the description of the fractal media that uses the fractional integrals. We derive the fractional generalizations of the equation that defines the medium mass. We prove that the fractional integrals can be used to describe the media with noninteger mass dimensions. The fractional equation of continuity is considered. PACS: 05.45.Df; 47.53.+n; 05.40.-a

In this study, we present new variants of the Hermite–Hadamard inequality via non-conformable fractional integrals. These inequalities are proven for convex functions and differentiable whose derivatives in absolute value generally convex. Our main results established using classical Jensen–Mercer its (h,m)-convex modified paper. addition to showing that our support previously known from litera...
