Complementary expressions for the entropy-from-work theorem.
We establish an expression of the entropy-from-work theorem that is complementary to the one originally proposed by Talkner, Hanggi, and Morillo [Phys. Rev. E 77, 051131 (2008)]. In the original expression the final energy is fixed, whereas in the present expression the initial energy is fixed.
