Completions &

 

Completion of the process is familiar:

 

 We can embed the original domain to the domain after Completion, we have to examine changes in valuation of:

 

 

 

 

 

 

Ostrowski Theorem tells us that the complete domain under archimedean valuation is certain:

 

 The conclusion is amazing, we focus to resolve its proof to prove that the use of reductio ad absurdum, the key to prove that the problem into a number of instructions on K necessarily satisfy a quadratic equation on R:
We first explain the real number field contained in R:

 

     

 

 

 

 

 

 

 

 

 

 

   So we emphasis on the nonarchimedan valuation,

 

 

 

The following two theorems but a p-adic promotion of:

 

 

 

  In the field of rational function on valuation prime ideal for complete power series of the form field is obtained:

 

 

  Secondly, with a projected limit can also be used in the theory of general valuation theory:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The key to remember is open neighborhood bases 0 element of two parts.

 

 

 

 

 

 

 

 

 

 

We valuation induction into the domain of algebraic extension of the above to:

 

 We focus on analytical proof of this theorem:

First, the case is not difficult to discuss the Archimedean and make a limited number of expansion:
