Mutsara 1: Musiyano mukuru pakati peCech cohomology ne sheaf cohomology inokurudzira kushandiswa kwe hypercoverings: izvi zvinhu zvinogoneka kupfuura Cech nerve. Mutsara wechipiri: Musiyano mukuru uripo pakati pe cech - cohomology ne yarrow - cohomology ndicho chikonzero chekushandisa hypercovering: izvi zvinhu zvinogoneka kupfuura cech - nerve. Mubvunzo: Mutsara wokutanga nomutsara wechipiri unoreva chinhu chimwe chete here? Hungu kana kuti Aiwa?
