Calculations for a general maximum principle: 1993 notes on the normalized parabolic $p$-Laplacian

This note makes available, in facsimile form, a set of handwritten notes from September 1993 devoted to Bochner-type maximum principle computations for a general class of quasilinear parabolic equations which contains, as a special instance, the normalized parabolic $p$-Laplacian \[ u_t = Δu + (p-2)
