The outline is the following:\n 1. Introduction to perturbative string theory\n  1.1 From point particle to extended objects\n  1.2 Free closed and open string spectrum\n  1.3 Compactification on a circle and T-duality\n  1.4 The Superstring: type IIA and IIB\n  1.5 Heterotic string and orbifold compactifications\n  1.6 Type I string theory\n  1.7 Effective field theories\n  References\n 2. Introduction to non-perturbative string theory\n  2.1 String solitons\n  2.2 Non-perturbative string dualities\n  2.3 M-"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/9906108","kind":"arxiv","version":2},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
