Abstract In this article, we consider the parabolic system ( u i ) t = ∇ ⋅ ( m U m − 1 A ( ∇ u i , u i , x , t ) + ℬ ( u i , x , t ) ) , ( 1 ≤ i ≤ k ) {({u}^{i})}_{t}= abla \cdot (m{U}^{m-1}{\mathcal{A}}( abla {u}^{i},{u}^{i},x,t)+{\mathcal{ {\mathcal B} }}({u}^{i},x,t)),\hspace{1.0em}(1\le i\le k) in the range of exponents m > n − 2 n m\gt \frac{n-2}{n} where the diffusion coefficient U U depends on the components of the solution u = ( u 1 , … , u k ) {\bf{u}}=({u}^{1},\ldots ,{u}^{k}) . Under suitable structure conditions on the vector fields A {\mathcal{A}} and
