The fluctuation theorem (FT) and the work relation (WR) are two relations that extend our understanding of thermodynamics to non-equilibrium systems. While often treated as distinct relations,they are in fact closely related. In this letter we generalise these relations,sho wing that they are fundamental relations of statistical systems,and use these generalised forms to connect the FT and WR through a new set of relations,the conjugate work relations. We then take these general forms of the FT and WR,and show that they reduce to original forms under deterministic dynamics,b efore finally exploring their application to an ...
