WebJun 5, 2024 · The trace of such an operator is defined as $ \sum \langle T \phi _ {j} , \phi _ {j} \rangle $, where $ \phi _ {j} $ is any orthonormal basis. The product of two Hilbert–Schmidt operators is of trace class and the converse is also true. The norm $ \ A \ $ in the above article is not the usual operator norm of $ A $ but its Hilbert–Schmidt ... WebDec 30, 2024 · Thus, your problem is reduced to finding the Hilbert class field of F. Magma (and presumably also Sage?) will just give it to you. It is the splitting field over Q of the cubic polynomial x 3 − x + 1. In summary, the Hilbert class field of K is obtained by adjoining to K a root of x 3 − x + 1. Share Cite Improve this answer Follow

WebRemark 2.1.5. At this point, it should now be apparent that class field theory is “class field” theory, i.e., the theory of class fields such as the Hilbert class fields (and other examples described in Definition 2.2.7) rather than a special type of “field theory”. Whether this affects your pronunciation of the entire phrase is up to you!

This means that $K$ already contains all the information about its abelian unramified extensions. This can be seen as a generalisation of quadratic reciprocity.
