Pointwise estimates for gradients of temperatures in terms of maximal functions
We give a detailed proof, in the case of one space dimension, of a pointwise upper estimate for the space gradient of a temperature. The operators involved are a one-sided maximal Hardy-Littlewood in time and the Calderón sharp maximal operator in space.
