From the introduction: "We continue here the investigation initiated earlier by us [Trans. Amer. Math. Soc. 314 (1989), no. 1, 187–224] concerning the solvability of the Cauchy problem and the existence of initial traces for nonnegative weak solutions of the nonlinear evolution equation (1) ut ? div(|Du| p?2 Du)=0 in ST ? RN ×(0,T), 02, both in terms of results and techniques. The main difference stems from the fact that, unlike solutions in the case p>2, solutions of (1) are not, in general, locally bounded.''
