complex analysis means to me ... analysis. cauchy-riemann, laurent series, residue theorem, etc. i only skimmed but this looks like just complex numbers. on the other hand here's a cool use of holomorphic maps (analytic in the plane or entire or differentiable at every point) to construct barycentric coordinates https://onlinelibrary.wiley.com/doi/full/10.1111/j.1467-8659.2011.02027.x?casa_token=ykAlTb57K5EAAAAA%3AzngF9nxkJeuW-NkQgoNeI6y7LLaVR_W41uN7hr5BCzTOvOrcbP8BTXdoapjQK0PEOAiNznu1D_vj1tU https://onlinelibrary.wiley.com/doi/full/10.1111/j.1467-8659...
