Abstract
In this paper we consider the following three-phase-lag thermoelastic plate: (Formula presented.) We obtain analyticity and exponential stability for the associated (Formula presented.) -semigroup when the coefficients satisfy (Formula presented.). The analyticity of the semigroup still holds when (Formula presented.). However, the instability of solution was proved by the Routh–Hurwitz rule.
