Two-Step Decoding of Binary $2 \times 2$ Sum-Rank-Metric Codes

Hao Wu, Bocong Chen, Guanghui Zhang +1

We address an open problem posed by Chen-Cheng-Qi (IEEE Trans.\ Inf.\ Theory, 2025): can the decoding of binary sum-rank-metric codes $\SR(C_1,C_2)$ with $2 \times 2$ matrix blocks b…

Regular Cyclic $(q + 1)$ -Arcs in $\PG(3,2^m)$: Spectral Rigidity, Descent, and an MDS Criterion

Bocong Chen, Jing Huang, Hao Wu

Let $q = 2^{m}$ with $m \geq 3$ and set $n := q + 1$ . We investigate $(q + 1)$ -arcs $A \subset PG (3, q)$ that admit a regular cyclic subgroup $C \leq PGL (4, q)$ of order…
