Partial exact controllability for the linear thermo-viscoelastic model

Electron. J. Differ. Equ. 1998, Paper No. 17, 11 p. (1998)


Summary: The problem of partial exact controllability for linear thermo-viscoelasticity is considered. Using classical multiplier techniques, a boundary observability inequality is established under smallness restrictions on coupling parameters and relaxation functions. Then, via the Hilbert Uniqueness method, the result of partial exact controllability is obtained with Dirichlet boundary controls acting on a part of the boundary of a domain.
