We give an algebraic characterization of half-factorial orders in algebraic number fields. This generalizes prior results for seminormal orders and for orders in quadratic number fields.

  1. On $q$-real and $q$-complex numbers

    math.CV 2025-08 unverdicted novelty 6.0 of 10

    For every real x > 1 the q-real series [x]_q converges in the disk |q| < 3−2√2 to a nonvanishing holomorphic function, partially proving the radius-convergence conjecture.

  2. Multiplicative Relationships of Subrings and their Applications to Factorization

    math.AC 2025-06 conditional novelty 6.0 of 10

    For orders in number fields, a subring is associated if and only if it is both ideal-preserving and locally associated, yielding a quadratic-order classification of half-factorial domains.
