integer matrices造句

Integer matrices are not limited to rotations; for example, a reflection is also a symmetry of order 2.
To state the restriction for all dimensions, it is convenient to shift attention away from rotations alone and concentrate on the integer matrices.
On the other hand, calculating homotopy was a bit of a spectral sequence nightmare, and calculating homology was just finitely generated abelian groups and row reducing integer matrices.
Integer matrices of determinant 1 form the group \ mathrm { SL } _ n ( \ mathbf { Z } ), which has far-reaching applications in arithmetic and geometry.
For instance, in topology, it can be used to compute the homology of a simplicial complex or CW complex over the integers, because the boundary maps in such a complex are just integer matrices.
It's difficult to find integer matrices in a sentence. 用integer matrices造句挺难的

The monodromy around each singular fiber is a well-defined conjugacy class in the group SL ( 2, "'Z "') of 2 ?2 integer matrices with determinant 1.
The relation between y and z above is an equivalence relation . ( This follows, for instance, because the above transformation gives a group action of the group of integer matrices with determinant 1 on the set S _ c . ) Thus, S _ c partitions into equivalence classes.
A congruence subgroup is ( roughly ) a subgroup of an arithmetic group defined by taking all matrices satisfying certain equations modulo an integer, for example the group of 2 by 2 integer matrices with diagonal ( respectively off-diagonal ) coefficients congruent to 1 ( respectively 0 ) modulo a positive integer.
