The transition matrix corresponding to $G$ is defined by $H(t):=\\exp{\\left(itA\\right)}$, $t\\in\\Rl$. The graph $G$ is said to have perfect state transfer (PST) from a vertex $u$ to another vertex $v$, if there exist $\\tau\\in\\Rl$ such that the $uv$-th entry of $H(\\tau)$ has unit modulus. The graph $G$ is said to be periodic at $\\tau\\in\\Rl$ if there exist $\\gamma\\in\\Cl$ with $|\\gamma|=1$ such that $H(\\tau)=\\gamma I$, where $I$ is the identity matrix. A $\\mathit{gcd}$-graph is a Cayley graph over a finite abelian group defined by greatest common diviso"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1601.07398","kind":"arxiv","version":1},"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"}
