摘要

我们证明了Shklyarov关于K.Saito的高残配对与矩阵分解范畴的周期循环同调上的某个配对之间关系的一个猜想。同时，我们给出了Shklyarov和Polishchuk-Vaintrob关于矩阵因子分解的Hirzebruch-Riemann-Roch公式的一个结果的新证明。

A proof of a conjecture of Shklyarov

We prove a conjecture of Shklyarov concerning the relationship between K. Saito's higher residue pairing and a certain pairing on the periodic cyclic homology of matrix factorization categories. Along the way, we give new proofs of a result of Shklyarov and Polishchuk-Vaintrob's Hirzebruch-Riemann-Roch formula for matrix factorizations.
