DOI 10.1007/0-387-29555-0_13 is Ushijima (sole author) —
"A Volume Formula for Generalised Hyperbolic Tetrahedra",
in: Prékopa & Molnár (eds.), Non-Euclidean Geometries,
Springer 2006. arXiv: math/0309216.
The references.md entry was wrong on all three counts:
- Author: "Meyerhoff, Ushijima" → Ushijima only
- Title: "A Note on the Dirichlet Domain" → entirely different title
- Book: "The Epstein Birthday Schrift" → Non-Euclidean Geometries
Same error pattern as the Kolpakov-Mednykh fix: the Java source
links only to a DOI without naming authors; a wrong name was
invented during the C++ port.
Files corrected: hyper_ideal_utility.hpp, hyper_ideal_functional.hpp,
