THE CALCULUS OF BIVARIATE FRACTAL INTERPOLATION SURFACES
Abstract
In this paper, we investigate partial integrals and partial derivatives of bivariate fractal interpolation functions (FIFs). We also prove that the mixed Riemann–Liouville fractional integral and derivative of order γ=(p,q);p>0,q>0γ=(p,q);p>0,q>0, of bivariate FIFs are again bivariate interpolation functions corresponding to some iterated function system (IFS). Furthermore, we discuss the integral transforms and fractional order integral transforms of the bivariate FIFs.
