connecting homomorphism造句

The connecting homomorphism sends a line bundle to its first Chern class.
The latter are called " connecting homomorphisms " and are provided by the zig-zag lemma.
There is also the connecting homomorphism from of the orthogonal group, to the of the kernel of the spin covering.
The connecting homomorphism is therefore a generalized winding number and measures the failure of " U " to be contractible.
We will use the spectral sequence of a filtered complex to find the connecting homomorphism and to prove that the resulting sequence is exact.
It's difficult to find connecting homomorphism in a sentence. 用connecting homomorphism造句挺难的

Kummer theory was another such early part of the theory, giving a description of the connecting homomorphism coming from the " m "-th power map.
The connecting homomorphism from, which is simply the group of-valued points, to is essentially the spinor norm, because is isomorphic to the multiplicative group of the field modulo squares.
If ? admitted a first derived functor, then exactness on the left would imply that the connecting homomorphism vanished, and this would certainly be true if the first derived functor of " f ", whatever it was, vanished.
