我们在奇异(mathfrak {gl}_{n})-范畴({mathcal O}_{n})上给出了(mathfrak {q}(2))-晶体的分类。我们的结果扩展了由Bernstein-Frenkel-Khovanov的工作导出的(mathfrak {gl}_{2})-晶体结构在(ext {Irr} ({mathcalo}_{n}))上。进一步讨论了({mathfrak q}(2))-晶体(ext {Irr} ({mathfrak O}_{n}))的性质。
We provide a categorification of (mathfrak {q}(2))-crystals on the singular (mathfrak {gl}_{n})-category ({mathcal O}_{n}). Our result extends the (mathfrak {gl}_{2})-crystal structure on ( ext {Irr} ({mathcal O}_{n})) induced from the work of Bernstein-Frenkel-Khovanov. Further properties of the ({mathfrak q}(2))-crystal ( ext {Irr} ({mathcal O}_{n})) are also discussed.
