A geometric model for non-uniform processes of morphogenesis

In this paper we present an application of the groupoid theory to the study of relevant case of material evolution phenomena, the $\mathit{\text{process}}\mathit{\text{of}}\mathit{\text{morphogenesis}}$. Our theory is inspired by Walter Noll’s theories of continuous distributions and provides a unifying and very simple framework of these phenomena. We present the explicit equation, the $\mathit{\text{morphogenesis}}\mathit{\text{equation}}$, to calculate the $\mathit{\text{material}}\mathit{\text{distributions}}$ associated to this phenomenon.
