Approximations for the Caputo Derivative (I)

Yuri Dimitrov

In this paper we construct approximations for the Caputo derivative of order $1 - α, 2 - α, 2$ and $3 - α$ . The approximations have weights $0.5 ((k + 1)^{- α} - (k - 1)^{- α}) /Γ (1 - α)$ a…

Approximations for the Caputo derivative (II)

Yuri Dimitrov, Venelin Todorov, Radan Miryanov

In the present paper we use the expansion formula of the polylogarithm function to construct approximations of the Caputo derivative which are related to the midpoint approximation…

Higher-Order Numerical Solutions of the Fractional Relaxation-Oscillation Equation using Fractional Integration

Yuri Dimitrov

In the present paper we derive the asymptotic expansion formula for the trapezoidal approximation of the fractional integral. We use the expansion formula to obtain approximations…
