In this paper an alternative definition, based on the geometric properties of a non-Minkowskian, non-Galilean but nevertheless boost-invariant, space-time structure is proposed. A \"duality\" with the Galilean limit $c\\to\\infty$ is established. Our theory is illustrated by Carrollian electromagnetism.","external_url":"https://arxiv.org/abs/1402.0657","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-24T06:03:58.335148+00:00","pith_arxiv_id":"1402.0657","created_at":"2026-05-10T12:30:23.536908+00:00","updated_at":"2026-05-24T06:03:58.335148+00:00","title_quality_ok":true,"display_title":"Carroll versus Newton and Galilei: two dual non-Einsteinian concepts of time","render_title":"Carroll versus Newton and Galilei: two dual non-Einsteinian concepts of time"},"hub":{"state":{"work_id":"28111acc-fb32-4c8f-8050-e6d4daa23423","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":13,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2023-11-17T14:59:43+00:00","last_pith_cited_at":"2026-05-07T18:00:04+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":"2026-05-25T03:45:27.591694+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":7}],"polarity_counts":[{"context_polarity":"background","n":7}],"runs":{},"summary":{},"graph":{},"authors":[]}}
