In summary, the conversation discusses the Galois Group and its realization over the field of rational numbers, specifically for a group with order p^n. It is mentioned that all solvable groups are known to be Galois groups, and the work of Shafarevich is brought up, which is considered to be the best work towards the Inverse Galois Problem. The possibility of obtaining a pdf version of this work is also mentioned. The conversation ends with a discussion on the relevance of Shafarevich's work if the Inverse Galois Problem is true.

Galois Group

Is [tex]G[/tex] realizable over [tex]\mathbb{Q}[/tex] given that [tex]|G|=p^n[/tex] ?

i think so. arent all solvable groups known to be galois groups? what did shafarevich prove?

Is it possible to have this in pdf? Thank you.

(Note: Shafarevich's theorem and work will be worthless if the Inverse Galois Problem is true. (Unless it depends breaking the group into solvable groups first)).

your note strikes me as odd. i would say shafarevich's work is more accurately described as the best work so far toward the inverse galois problem.

see the book of serre, topics in galois theory.

Get a (free) ps viewer, or run ps2pdf (standard *nix program, and installed if you have LaTeX on Win).

Your last comment seems to be yet another of your over-arching and dismissive comments about mathematics. These are strange since you seem to know a lot of number theory. How can you dismiss this work as being worthlesss if IGP is true? Surely you must then think all mathematics is worthless if it doesn't prove absolutely everything simultaneously?

Is it solved for abelian extensions?
 

What is a Galois Solvable Group?

A Galois Solvable Group is a type of mathematical group that is defined and studied in the field of Galois theory. It is a group that can be built up by a sequence of cyclic extensions, and can be used to solve polynomial equations.

How is a Galois Solvable Group related to Galois Theory?

Galois Solvable Groups are specifically studied in Galois theory as they provide important insights into the solvability of polynomial equations. They are often used to describe the solvable subgroups of the Galois group of a particular equation.

What properties do Galois Solvable Groups have?

Galois Solvable Groups have several important properties, including being a non-abelian group, having a normal series consisting of abelian groups, and being a solvable group. They also have a unique composition series, and their order is always a power of a prime number.

How are Galois Solvable Groups different from other types of groups?

Galois Solvable Groups are different from other types of groups, such as simple or nilpotent groups, in that they have a normal series consisting of abelian groups. This means that their subgroups are all normal and abelian, which allows for certain simplifications in their study and applications.

What are some real-world applications of Galois Solvable Groups?

Galois Solvable Groups have a wide range of applications in mathematics and other fields. Some examples include their use in solving polynomial equations, cryptography, and Galois cohomology. They also have connections to other areas of mathematics such as number theory and algebraic geometry.
