In particular, we construct several simplest spinor-oscillator representations and compute their highest weights for the 'stringy' Lie superalgebras (i.e., Lie superalgebras of complex vector fields (or their nontrivial central extensions) on the supercircle $S^{1|n}$ and its two-sheeted cover associated with the Möbius bundle).27 p., LatexRepresentation Theory22E45, 17B (Primary) 11E57, 15A72, 20G05, 22E47 (Secondary)text
