We give counterexamples to the degeneration of the Hochschild-Kostant-Rosenberg spectral sequence in characteristic p , both in the untwisted and twisted settings. We also prove that the de Rham-HP and crystalline-TP spectral sequences need not degenerate.

特征 p 中 Hochschild-Kostant-Rosenberg 的反例
我们给出了Hochschild-Kostant-Rosenberg谱序列特征退化的反例p ,在未扭曲和扭曲的设置中。我们还证明了 de Rham-HP 和晶体-TP 光谱序列不需要退化。
