摘要

Systems can be decomposed into a set of subsystems, where the dynamics of each subsystem only depends on some of the other subsystems rather than on all of them. Here I derive an infinite set of lower bounds on the 熵 production of any such composite system, in terms of the initial distribution of its states, the ending distribution, and the dependencies of the dynamics of its sub- systems. In contrast to previous results, these new bounds hold for arbitrary dependencies among the subsystems, not only for the case where the subsystems evolve independently. Moreover, find- ing the strongest of these new lower bounds is a linear programming problem. As I illustrate, often this maximal lower bound is stronger than the conventional Landauer bound, since the conventional Landauer bound does not
