摘要
In recent years different aspects of categorification of the boson-fermion correspondence have been studied. In this paper we propose a categorification of the boson-fermion correspondence based on the category of tensor modules of the Lie algebra sl(a) of finitary infinite matrices. By we denote the category of "polynomial" tensor sl(a)-modules. There is a natural "creation" functor , . The key idea of the paper is to employ the entire category of tensor sl(a)-modules in order to define the "annihilation" functor corresponding to . We show that the relations allowing one to express fermions via bosons arise from relations in the cohomology of complexes of linear endofunctors on T+.
