‎\noindent This ongoing work on Homotopic Deviation focuses on the purely‎ ‎algebraic aspect of the theory. We use the definition $\ds (zI - A)^{-1} =‎ ‎\frac{1}{\pi(z)} adj(zI - A) $ for $z \in re(A)=\C \backslash \sigma(A)$,‎ ‎$\pi(z)=$det$(zI-A)$, ~to ~relate $ M_z = V^H (zI - A)^{-1} U $ ~to ~the‎ ‎~matrix ~polynomial $Q(z) = V^H adj (zI - A ) U$ of order $ r
