This review covers the generalized Galileons, (the rediscovery of) the Horndeski theory, cosmological perturbations in the Horndeski theory, cosmology with a violation of the null energy condition, degenerate higher-order scalar-tensor theories and their status after GW170817, the Vainshtein mechanism in the Horndeski theory and beyond, and hairy black hole solutions.","external_url":"https://arxiv.org/abs/1901.07183","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-19T08:52:13.359086+00:00","pith_arxiv_id":"1901.07183","created_at":"2026-05-09T06:10:39.089113+00:00","updated_at":"2026-05-19T08:52:13.359086+00:00","title_quality_ok":true,"display_title":"Kobayashi, Horndeski theory and beyond: a review, Rept","render_title":"Kobayashi, Horndeski theory and beyond: a review, Rept"},"hub":{"state":{"work_id":"562adcc5-e3a0-4e13-829f-2c988a0d91ba","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":23,"external_cited_by_count":null,"distinct_field_count":3,"first_pith_cited_at":"2025-06-17T18:00:01+00:00","last_pith_cited_at":"2026-05-08T14:17:06+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":"2026-05-25T20:45:59.511481+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":12}],"polarity_counts":[{"context_polarity":"background","n":12}],"runs":{},"summary":{},"graph":{},"authors":[]}}
