Abstract: | In this paper, using the third-order WKB approximation, we
investigate the quasinormal frequencies of the scalar field in the
background of a five-dimensional Lovelock black hole. We find that the
ultraviolet correction to Einstein theory in the Lovelock theory
makes the scalar field decay more slowly and
oscillate more quickly, and the cosmological constant makes the
scalar field decay more slowly and oscillate
more slowly in the Lovelock black hole background. |
