?Mathematical Reviews
Written in a unique and accessible style for readers of varied
mathematical backgrounds, the Second Edition of Primes of
the Form p = x2+ ny2
details the history behind how Pierre de Fermat?s work
ultimately gave birth to quadratic reciprocity and the genus theory
of quadratic forms. The book also illustrates how results of Euler
and Gauss can be fully understood only in the context of class
field theory, and in addition, explores a selection of the
magnificent formulas of complex multiplication.
Primes of the Form p = x2 +
ny2, Second Edition focuses on
addressing the question of when a prime p is of the form
x2 + ny2,
which serves as the basis for further discussion of various
mathematical topics. This updated edition has several new notable
features, including:
? A well-motivated introduction to the classical
formulation of class field theory
? Illustrations of explicit numerical examples to
demonstrate the power of basic theorems in various situations
? An elementary treatment of quadratic forms and genus
theory
? Simultaneous treatment of elementary and advanced
aspects of number theory
? New coverage of the Shimura reciprocity law and a
selection of recent work in an updated bibli

Good value, but buyers should be aware that the metal base extends only on edges
I think this tray is a good value compared to other vendor's products that are $100+. I plan to keep it because it is a good value for me. HOWEVER, realize that the metal base does not extend across the full base of the cork liner. Metal pieces are only on the edge of long side of the liner. Also, the metal is lightweight.

The Ideal Organizer
The UPERGO Valet Tray is an ideal size for my nightstand. It does not slide around but stays put where I position it. Each section is useful for the items I want to keep close at hand but in an organized fashion, cell phone, wallet glasses, change, etc. I love the cork interior of the tray; it’s stylish and functional.

It's a functional organizational tray
I bought this valet tray for my nephew to be able to organize his go-to items, such as his cell phone, wallet, watch, bracelet, etc. I expected the tray to look more upgraded. The compartments are shallow, but they do the job. It is made of a cardboard-type material ( corkboard would have been nicer), and the black platform is a metal construction, which gives it a more stable and solid structure. Overall, for the price and its functionality, I guess it was worth the purchase.
