## Uniqueness and Hölder type stability of continuation for the linear thermoelasticity system with residual stress

 1 Wichita State University, 1845 Fairmount, Wichita, KS 67260-0033, United States

By introducing some auxiliary functions, an elasticity system with thermal effects becomes a coupled hyperbolic-parabolic system. Using this reduced system, we obtain a Carleman estimate with two large parameters for the linear thermoelasticity system with residual stress which is the basic tool for showing stability estimates in the lateral Cauchy problem.
