Dynamic and quasi-electromagnetostatic evolution of a thermoelectromagnetoelastic body

A standard technique of evolution equations in Hilbert spaces of possible states with finite energy supplies results of existence and uniqueness for the dynamic evolution of a thermoelectromagnetoelastic body and for its ''quasi-electromagnetostatic approximation''  whose relevance is established through a convergence result as a parameter, accounting for the ratio of the speed of elastic wave propagation to the celerity of the light, goes to zero.
