A uniqueness theorem for the solutions to the initial boundary value problem, the generalized Hamilton principle and a theorem of reciprocity of work are deduced for incremental fields superposed on finite biasing fields in a thermoelectroelastic body.Version 1: about 12 pages. Version 2: 22 pages. Version 2 is a generalization of version 1 since it also contains a generalized Hamilton principle and a theorem of reciprocity of workMathematical Physics74F99text
