Y. Shenker et al., ON THE EXPONENTIAL TEMPORAL DECAY OF SOLUTIONS AND THEIR DERIVATIVES FOR QUASI-LINEAR PARABOLIC EQUATIONS, Zeitschrift fur angewandte Mathematik und Physik, 46(2), 1995, pp. 198-223
A nonlinear model for temperature evolution in a one-dimensional rod i
s considered. Integral and uniform pointwise temporal exponential deca
y estimates for the solution and its derivatives are obtained. A metho
d is demonstrated for derivatives up to the third order but seems to a
pply for derivatives of any order as well.
