在本文中,我们重温Celikbas和Takahashi关于模的张量积的自反性的一个例子。我们研究了Tor-rigidity和顶点由极小素理想组成的Hochster-Huneke图,并确定了上述例子不发生的条件。我们的结果特别证实了Huneke和Wiegand的第二刚性定理。
In this paper we revisit an example of Celikbas and Takahashi concerning the reflexivity of tensor products of modules. We study Tor-rigidity and the Hochster–Huneke graph with vertices consisting of minimal prime ideals, and determine a condition with which the aforementioned example cannot occur. Our result, in particular, corroborates the Second Rigidity Theorem of Huneke and Wiegand.
