Exponential decay for a neutral wave equation
Nasser-eddine M. Tatar
Keywords:Exponential decay, modified energy, multiplier technique, neutral delay, stability.
Abstract:
      A strongly damped wave equation involving a delay of neutral type in its second order derivative is considered. It is proved that solutions decay to zero exponentially despite the fact that delays are, in general, sources of instability.
