备  注：We study Tate-Vogel and relative cohomlogies of complexes of modules over a ring based on flats. When the ring is right coherent, we give general techniques for computing those cohomologies of complexes of finite Gorenstein flat dimension. Moreover, we get an Avramov-Martsinkovsky exact sequence for complexes of finite Gorenstein flat dimension, connecting relative and Tate-Vogel cohomologies via a long exact sequence.
