2. Distribution of entropy production in space and time

2.1 Equipartition theorem

This paragraph is devoted to proving the following general but somewhat abstract theorem, and to explaining its consequences.

Equipartition theorem

Under the linear assumptions of the thermodynamics of irreversible processes, for a specified task in a process, global entropy production is minimal when local production is uniformly distributed in time and space (i.e., equi-distributed).

In the language adopted here, "equipartition" of a quantity along a coordinate means that the local value, or density, of that quantity is constant along the coordinate.

We will now particularize this demonstration to the linear geometry...
