我们考虑带分数阻尼项的波动方程在${bf R}^{n}$中的柯西问题。我们部分地推广了文[12]中的结果,并基于傅里叶空间中的能量方法得到了解的总能量和$L^{2}-范数的精确衰减估计。
We consider the Cauchy problem in ${\bf R}^{n}$ for wave equations with a fractional damping. We generalize partially the previous results due to[12], and derive sharp decay estimates for the total energy and the $L^{2}$-norm of solutions based on the energy method in the Fourier space.
