线性范畴的迹或第 0 次 Hochschild-Mitchell 同调可以被视为一种去范畴化。我们计算了第三作者引入的两个版本和分类量子的踪迹。的迹与分裂的格洛腾迪克群同构,并且更高的霍克希尔德-米切尔同调性为零。 of 的迹同构于当前代数的幂等积分形式。
The trace or the 0th Hochschild–Mitchell homology of a linear categorymay be regarded as a kind of decategorification of. We compute the traces of the two versionsandof categorified quantumintroduced by the third author. The trace ofis isomorphic to the split Grothendieck group, and the higher Hochschild–Mitchell homology ofis zero. The trace ofis isomorphic to the idempotented integral form of the current algebra.
