Dissipative entropy makes the heat equation hyperbolic

Paolo Podio-Guidugli


Infinite disturbance speed, an undesirable feature of the standard heat equation, is usually avoided by assuming a Boltzmann-Volterra dependence of the heat influx vector on the history of the temperature gradient. It is shown in this paper how to attain the same desideratum by postulating a constitutive splitting of entropy into standard and dissipative parts.
