在这份报纸,我们调查对波色子振荡器的范畴的描述。基于 Khovanov 构造的范畴,我们介绍 Fock 状态和这些状态的相应内部产品的 categorification。我们发现有 Fock 状态的内部产品的二个不同范畴的定义。这二个定义与对方一致,并且 decategorification 结果也在常规量力学与那些与一致。我们也发现有联系到状态的内部产品的 2-morphisms 的一些有趣的性质。
In this paper, we investigate the categorical description of the boson oscillator. Based on the categories constructed by Khovanov, we introduce a categorification of the Fock states and the corresponding inner product of these states. We find that there are two different categorical definitions of the inner product of the Fock states. These two definitions are consistent with each other, and the decategorification results also coincide with those in conventional quantum mechanics. We also find that there are some interesting properties of the 2-morphisms which relate to the inner product of the states.
