Higher-spin gauge models with (1, 1) supersymmetry in AdS3 : Reduction to (1, 0) superspace

In three dimensions, there are two types of ${\cal N}=2$ anti-de Sitter (AdS) supersymmetry, which denoted (1,1) and (2,0). They characterised by different supercurrents support families higher-spin gauge models (massless massive) were constructed in arXiv:1807.09098 arXiv:1809.00802 for the (2,0) cases, respectively, using superspace techniques. It turns out that precise difference between supermultiplets can be pinned down reducing these theories to (1,0) AdS superspace. The present paper is devoted $(1,1) \to (1,0)$ reduction. conjunction with outcomes $(2,0) reduction carried arXiv:1905.05050, we demonstrate every known theory or supersymmetry decomposes into a sum off-shell belong four series inequivalent models. latter reduced components.
