Question

I wanna learn Gallois theory and sparse matrices in detail . Any online help.

Answer 1

A method of applying group theory to the solution of algebraic equations.

Answer 2

Example #1: K = Q, L = Q(SQRT(n)) for any squarefree integer n. The minimal polynomial of SQRT(n) is x^2 – n; L is obviously normal over K, so it’s Galois and the fundamental theorem applies. The degree of L over K is 2, so Gal(L/K) has order 2. There is only one group of size 2, Z/2Z. That group has only two subgroups, the improper subgroup consisting of the entire group and the trivial subgroup consisting of the identity element 0. The non-identity element of the Galois group is the automorphism sending a + bSQRT(n) to a – bSQRT(n). thats the gallois theory

Answer 4

mam can you suggest me some books on these topics ?
Actually I am studying networking from tanenbaum and wanna go furthur along with java

Answer 5

im sorry i dont know any books

Answer 6

But you know gallios theory! Thanx.

Answer 7

yw

Answer 8

How you could learn it?

Answer 9

I think that will be easier for me to get through it

Answer 10

well i was taught lol
i didnt read it from a book

Answer 16

Well if you dont mind can i know whether profile pic is yours!

Answer 17

and what about sparse matrices?

Answer 18

yea it is lol

Answer 19

and i cant help you with sparse matrices because i dont know tht

Answer 20

why always lol? ho can you say that i am lol?

Answer 21

i dnt understand what your trying to say.........

Answer 22

really good that you dont know sparse matrices or else it had been ended in a paragraph

Answer 23

i meant what does lol mean?

Answer 24

it is really hard for a beginner to understand mathematics in a paragraph, i hope you can imagine

Answer 25

oh it means laugh out loud
we just say it to be friendly

Answer 26

you take a long time to reply. Is it usual?

Answer 27

yes :)

Answer 28
