I'm considering the following type of PDE: $u_{t}=u_{xx}+u_{x}+u_{x}^2+u_{x}^3+\frac{u_{x}}{x(1-x)}+\left(\frac{u_{x}}{x(1-x)}\right)^3$
with periodic boundary conditions $u_{x}(0,t)=u_{x}(1,t)=0$, $u(x,0)=u_{0}:S^{1}\rightarrow\mathbb{R}.$
Does anyone know of literature/articles I can look at to possibly show local existence(or blow up?). I've spent quite a bit of time looking through literature in particular Henry's Geometric theory of Semi-Linear Parabolic equations and papers by H.Amman on Quasi linear Parabolic equations. Also due to the singularity I considered a weighted sobolev space approach but had no success. I apologize if I'm too vague.
