The schematic description of the growth in elasticity. $(g_{r}R,g_{\mathit{\theta }}\mathit{\Theta })$ represents the grown configuration in the reference coordinate system $(R,\mathit{\Theta })$ after the mapping ${\mathbf{F}}_{\mathbf{g}}$ while $(g_{r}R,\mathit{\theta })$ represents the intermediate configuration in the mixed coordinate system $(R,\mathit{\theta })$ after the mapping ${\mathbf{F}}_{\mathbf{e}\mathbf{2}}$
