发帖数: 32 | 2 Yes. There is a canonical isomorphism between them.
Use the fact that N_p=N\otimes_A A_p, for any A module N, and the
associativity:
(M\otimes N)\otimes O=M\otimes(N\otimes O) |

ISIS制备了阿德纳尼与替身的纠缠态
|阿德纳尼（r1）>\otimes|替身（r2）> + |替身(r1)>\otimes|阿德纳尼(r2)>
不管炸r1还是r2都只有一半的几率炸死
所以我帝跟鹅毛就合作了一把，一起炸，我帝跟鹅毛都有1/2的几率在说谎

发帖数: 752 | 4 first of all, it's not sth. can be explain all in a sudden
an example is about multiple electron spins, or taking the obital and spin
angular momentum together for 1 electron
in that case, a rotation can be written into tensor product form
D(total) = D(obital) \otimes D(spin)
or
D(2 electron) = D(1st) \otimes D(2nd)
in general, all matrix entries of D are not 0, which is not good for realistic
calculation. it is then found if we go to the irriducible representation, D
can be written into block-d |

构造出来 |

V^*\otimes V 里面的元素才叫 (1,1) 型张量 |

发帖数: 5600 | 10 Seems to be a perfect example of the "cyclic tridiagonal matrix".
You can solve it using the sherman-morrison formula
which tells you how to invert A+u\otimes v.
See Sec 2.7 (p73-75) in Numerical Recipes in C
for details of S-M formula and code for inversion of
cyclic tridigonal matrix.
-Z. |

x*****d
发帖数: 427 | 11 xy: V --> V
xy(z)=(y.z)x here . means scalar product.
So it's basicly a linear transformation.
If you want a tensor form, that will be x \otimes y*
where y* is the conjugate element of y in V*: y*(z)=y.z |

发帖数: 255 | 12 Do you mean the Kronecker product?
It is denoted by "\otimes" in latex.
similar to (X) |
