Published in 2021 at "Journal of Optimization Theory and Applications"

DOI: 10.1007/s10957-021-01829-8

Abstract: In this paper, we study robust necessary optimality conditions for a nondifferentiable complex fractional programming with uncertain data. A robust counterpart of uncertain complex fractional programming is introduced in the worst-case scenario. The concept of… read more here.

Published in 2018 at "Probabilistic Engineering Mechanics"

DOI: 10.1016/j.probengmech.2018.05.005

Abstract: Abstract Recently, the concept of complex fractional moments has been introduced as an extension to ordinary moments. It has been shown that complex fractional moments never diverge and they are able to represent both probability… read more here.

Published in 2018 at "Fractional Calculus and Applied Analysis"

DOI: 10.1515/fca-2018-0069

Abstract: Abstract The classical wave equation is generalized within fractional framework, by using fractional derivatives of real and complex order in the constitutive equation, so that it describes wave propagation in one dimensional infinite viscoelastic rod.… read more here.
