The perturbations are considered both in frequency and time domain. The dependence of the scalar field evolution on the values of the cosmological constant $\\Lambda$ and the Gauss-Bonnet coupling $\\alpha$ is investigated. For Gauss-Bonnet and Gauss-Bonnet-de Sitter black holes, at asymptotically late times either power-law or exponential tails dominate, while for Gauss-Bonnet-anti-de Sitter black hole, the quasinormal modes govern the scalar field decay at all times. The power-law tails at asymptotically late times for odd-dimensional Gauss-Bonnet black holes does not depend on $\\alpha$, even though the black hole metric contains $\\alpha$ as a new parameter. The corrections to quasinormal spectrum due to Gauss-Bonnet coupling is not small and should not be neglected. For the limit of near extremal value of the (positive) cosmological constant and pure de Sitter and anti-de Sitter modes in Gauss-Bonnet gravity we have found analytical expressions.","external_url":"https://arxiv.org/abs/hep-th/0507100","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T07:26:41.911984+00:00","pith_arxiv_id":"hep-th/0507100","created_at":"2026-05-11T11:06:02.396248+00:00","updated_at":"2026-06-05T21:23:00.469572+00:00","title_quality_ok":true,"display_title":"Scalar field evolution in Gauss-Bonnet black holes","render_title":"Scalar field evolution in Gauss-Bonnet black holes"},"hub":{"state":{"work_id":"c42bed49-655b-413c-abd2-707de24113b7","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":10,"external_cited_by_count":null,"distinct_field_count":1,"first_pith_cited_at":"2011-02-19T18:38:22+00:00","last_pith_cited_at":"2026-05-12T00:34:59+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-05-27T08:37:39.794976+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":6},{"context_role":"method","n":2}],"polarity_counts":[{"context_polarity":"background","n":5},{"context_polarity":"use_method","n":2},{"context_polarity":"unclear","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
