  We analyze the well-posedness of an anisotropic, nonlocal diffusion equation.
Establishing an equivalence between weighted and unweighted anisotropic
nonlocal diffusion operators in the vein of unified nonlocal vector calculus,
we apply our analysis to a class of fractional-order operators and present
rigorous estimates for the solution of the corresponding anisotropic anomalous
diffusion equation. Furthermore, we extend our analysis to the anisotropic
diffusion-advection equation and prove well-posedness for fractional orders s
in [0.5,1). We also present an application of the advection-diffusion equation
to anomalous transport of solutes.
