Magana ta 1: Bambanci na musamman tsakanin cohomology na Cech da cohomology na sheaf shine dalili don yin amfani da hypercoverings: waɗannan abubuwa ne masu yiwuwa fiye da jijiyar Cech. Magana ta 2: Bambanci tsakanin cech - cohomology da yarrow - cohomology shine dalili na yin amfani da hypercovering: waɗannan abubuwa ne masu yiwuwa fiye da cech - jijiya. Tambaya: Shin jumlar 1 da jumlar 2 suna bayyana ma'ana iri ɗaya? Shin ko a'a?
