Abstract
This paper is concerned with the gradient blowup rate for the onedimensional pLaplacian parabolic equation u t=u xp2 u x x +u xq with q p 2 for which the spatial derivative of solutions becomes unbounded in finite time while the solutions themselves remain bounded We establish the blowup rate estimates of lower and upper bounds and show that in this case the blowup rate does not match the selfsimilar one
