The volume–determinant inequality for alternating ARA braid closures
I prove the volume–determinant inequality for a family of alternating braid closures with arbitrarily many strands, arbitrarily many motifs, and independent integral twist exponents at least three. Each motif uses the adjacent generators in increasing, decreasing, and increasing order. No periodicity of the exponents or parity condition is imposed, and knots and links are both included. For a closure with m motifs, the proof gives 2π log det L − vol(S3 ∖ L) > m/50. A single motif is treated by a marked belted-sum decomposition of a partially augmented parent. For repeated motifs, positive transfer matrices give a uniform two-motif bound. Reciprocal spectra settle odd strand numbers; a retained unit mode, positive compound matrices, and a width-truncation argument settle even strand numbers. Exact integer and rational certificates, local triangulations and verification programs are specified in the appendices and supplied with the sources.
