An invariant-theoretic approach to three weight enumerators of self-dual quantum codes

Yin Chen, Shan Ren, Runxuan Zhang

This article is a continuation of our recent work (Yin Chen and Runxuan Zhang, Shape enumerators of self-dual NRT codes over finite fields. SIAM J. Discrete Math. 38 (2024), no. 4,…

Modular matrix invariants under some transpose actions

Yin Chen, Shan Ren

Consider the special linear group of degree $2$ over an arbitrary finite field, acting on the full space of $2 \times 2$ -matrices by transpose. We explicitly construct a generating…

Rota-Baxter operators on $I ¨ $ -Lie algebras

Yin Chen, Shan Ren, Jiawen Shan +1

This article explores Rota-Baxter operators on finite-dimensional $I ¨ $ -Lie algebras over a field of characteristic not 2. We provide several methods for constructing left-symmetric…

Generalized derivations of $I ¨ $ -Lie algebras

Yin Chen, Shan Ren, Jiawen Shan +1

This article explores the structure theory of compatible generalized derivations of finite-dimensional $I ¨ $ -Lie algebras over a field $K$ . We prove that any compatible qua…
