Abstract:
Two equations of state of a solid with the use of the fractional Riemann–Liouville derivative are obtained. Both equations are low-parametric (without involving a large number of adjustable parameters). In the proposed approach, the main task is to determine the parameters of the equation from the experimental data of the phase diagrams of the investigated substances.
Keywords:equation of state of matter, fractional derivative of Riemann–Liouville, fractal structure of matter.
