Fibonacci is known in particular due to the notion of the golden ratio, which has found great success in modeling natural phenomena. Also, based on this ratio, the Fibonacci polynomials emerged, which are employed in this work to establish an innovative family of fractional kernels. After showing that the family of kernels is well defined, we define two fractional derivatives, one of Caputo type and one of Riemann–Liouville type. Next, we demonstrate certain bound characteristics that the newly defined derivatives have. We also define the associated fractional integral for one of the family members of the newly defined derivative. Using the method of Laplace transform, we found explicit solutions for electrical circuits, using the fractional derivative introduced in this work.
期刊介绍:
The Journal of Computational and Applied Mathematics publishes original papers of high scientific value in all areas of computational and applied mathematics. The main interest of the Journal is in papers that describe and analyze new computational techniques for solving scientific or engineering problems. Also the improved analysis, including the effectiveness and applicability, of existing methods and algorithms is of importance. The computational efficiency (e.g. the convergence, stability, accuracy, ...) should be proved and illustrated by nontrivial numerical examples. Papers describing only variants of existing methods, without adding significant new computational properties are not of interest.
The audience consists of: applied mathematicians, numerical analysts, computational scientists and engineers.
