Thanks you help me well
How Prove that GL(2,R)/SL(2,R) is isomorphic to R* ?
Inverse of 3 is 5...how we will know mam?
This is a group for multiplication so take 3*1=3,3*2=6,3*3=9,3*4=12,3*5=15...now apply modulo 7 now elements will be 9/7=2,12/7=5,15/7=1....a*a^-1=identity=1(multiplication)
How is the first example an example for Sl(2,R) if Z5 isnt even a subset of R? Because Z5 consists of elements that are Sets of Integers, right? Isnt this a contradiction to the definition of Sl(2,R)?
Actually symbol of special type matrix is SL(2,F) ......or R,Q,C,Zp are field so entries of special type matrix are also belonging from R,Zp...
I hope you are getting my point
