On Artin Cokernel of The Quaternion Group Q2m When m=2^h ,h any positive integers Number
Keywords:
Artin cokernel, Quaternion group, cyclic decomposition, Artin charactersAbstract
In this article we find the cyclic decomposition of the finite abelian factor group AC(G)= R (G)/T(G) where G = Q2m and 2h m ,
h any positive integers and Q2m is the Quaternion group of order 4m.
(the group of all Z-valued generalized characters of G over the group of induced unit characters from all cyclic subgroups of G) .
We find that the cyclic decomposition AC(Q2m) depends on the elementary divisor of m
If 2h m , h any positive integers , then :
AC(Q2m)=1
1
h
i
C2
Moreover, we have also found the general form of Artin characters table Ar(Q2m) when m is an even number .
