High-order Compact Difference Schemes for the Modified Anomalous Subdiffusion Equation [PDF]
In this paper, two kinds of high-order compact finite difference schemes for second-order derivative are developed. Then a second-order numerical scheme for Riemann-Liouvile derivative is established based on fractional center difference operator.

Construction of Nordsieck Second Derivative General Linear Methods with Inherent Quadratic Stability
This paper describes the construction of second derivative general linear methods in Nordsieck form with stability properties determined by quadratic stability functions. This is achieved by imposing the so–called inherent quadratic stability conditions.

Optimal One-Point Iterative Function Free from Derivatives for Multiple Roots
We suggest a derivative-free optimal method of second order which is a new version of a modification of Newton’s method for achieving the multiple zeros of nonlinear single variable functions.

Trigonometrically-fitted second derivative method for oscillatory problems [PDF]
A continuous Trigonometrically-fitted Second Derivative Method (CTSDM) whose coefficients depend on the frequency and stepsize is constructed using trigonometric basis functions. A discrete Trigonometrically-fitted second derivative method (TSDM) is recovered from the CTSDM as a by-product and applied to solve initial value problems (IVPs) with ...

Study on SPH Viscosity Term Formulations [PDF]
For viscosity-dominated flows, the viscous effect plays a much more important role. Since the viscosity term in SPH-governing (Smoothed Particle Hydrodynamics) equations involves the discretization of a second-order derivative, its treatment could be ...

Ostrogradski Formalism for Higher-Derivative Scalar Field Theories [PDF]
We carry out the extension of the Ostrogradski method to relativistic field theories. Higher-derivative Lagrangians reduce to second differential-order with one explicit independent field for each degree of freedom.
