本文构造了无扭N= 2超共形代数上的一类非权模。当这些模被看作是Cartan子代数上的模(模中心)时,它们没有秩2。我们给出了这类模的同构类的分类。此外,这些模块的所有子模块被精确地确定。特别是,这些模块并不简单。对相应的单商模进行了分类。此外,这些简单的模时,限制为模在N= 1超共形代数一致的那些模块在杨等。(2020)[27]。
In this paper, we construct a family of non-weight modules over the untwisted N= 2 superconformal algebras. Those modules when regarded as modules over the Cartan subalgebra (modulo the center) are free of rank 2. We give a classification of isomorphism classes of such modules. Moreover, all submodules of such modules are precisely determined. In particular, those modules are not simple. The corresponding simple quotient modules are classified. Furthermore, these simple modules when restricted as modules over N= 1 superconformal algebras coincide with those modules constructed in Yang et al.(2020)[27].
