ERRATUM: CHIC: Cayley-Hamilton, invariants and constants for neutrino oscillation (2026 J. Phys. G: Nucl. Part. Phys. 53 075002)
We use the Cayley-Hamilton theorem to derive analytic solutions for three-flavor neutrino propagation amplitude in a constant-density medium and their derivative with respect to the mixing parameters. This approach avoids Hamiltonian diagonalization and exploits precomputed matrix invariants to separate the dependenc...
