A straightforward procedure reveals that although such a system may have negative energy, it is stable. In the quantized theory the vacuum state has to be suitably defined and then the zero-point energy corresponding to a positive-signature component is canceled by the one corresponding to a negative-signature component. This principle is then applied to a system of scalar fields. The metric in the space of fields is assumed to have signature (+ + + ... - - -) and it is shown that the vacuum energy, and consequently the cosmological","authors_text":"Matej Pavsic","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"1998-12-15T13:14:49Z","title":"Pseudo Euclidean-Signature Harmonic Oscillator, Quantum Field Theory and Vanishing Cosmological Constant"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/9812123","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:d8503ca2359bbe36c57578a5bef8308e3f32323ab03b7fe3a9636f2420a5ada7","target":"record","created_at":"2026-05-18T01:38:35Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"1ca876eef2a1a3ae86f4f935c156882def94628d23638e2ea6076ec546c9cc8a","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"1998-12-15T13:14:49Z","title_canon_sha256":"2c5818ea4bab264d1e2ec8e7a8187f4ca5e291c8b70747f3b770cdaa092c2e61"},"schema_version":"1.0","source":{"id":"hep-th/9812123","kind":"arxiv","version":1}},"canonical_sha256":"1b1ac27a6d3f41f01cffb65a582b7a23883ba4693c71c604f323c9d6de6252a9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1b1ac27a6d3f41f01cffb65a582b7a23883ba4693c71c604f323c9d6de6252a9","first_computed_at":"2026-05-18T01:38:35.340115Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:38:35.340115Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uoqeLuN3QuRwul23+X7q4N3lKnG1jVNfrI6F3y4x9/XF8sGxBjc/T2abG8HXT0OJWC7D8bfypmYGjrNBN4eSBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:38:35.340745Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/9812123","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d8503ca2359bbe36c57578a5bef8308e3f32323ab03b7fe3a9636f2420a5ada7","sha256:da9c3d5e09f89e0bb518f27c5a91e0689d8684bc625a9baad7feee32352ae5e7"],"state_sha256":"94a744ee1e35da9e6a1dbd58054019d2832a21159c55fba7186b1218f0ea1343"}
