Existence of a Renormalized Solution for a Class of Parabolic Problems

In the paper, we prove the existence of the renormalized solution for the nonlinear degenerate parabolic equation $\frac{\partial b(u)}{\partial t}-\textrm{div}(A(t,x,u)Du)=f,$ where the matrix $A\left( t,x,s\right) =\left(a_{ij}(t,x,s)\right)_{1\leq i\leq N \atop 1\leq j\leq N}$ is not controlled w...
