Abstract
This paper proposes a novel decoupling limit of the membrane, leading to the ( 1 + 2 )-dimensional classically integrable model originally introduced by Manakov, Zakharov, and Ward. This limit is the large-wrapping regime of a membrane propagating toy background of the form R t × T 2 × G subject to scaling limit, where G is a Lie group and the geometry is supported by a four-form flux. Such toy backgrounds can arise from consistent eleven-dimensional supergravity solutions, exemplified by the uplift of the pure Neveu-Schwarz-Neveu-Schwarz AdS 3 × S 3 × T 4 background. The scaling limit can be interpreted as a simultaneous small tension and non- or hyperrelativistic limit.
