this problem is about abstract algebra, especially is group theory.
Let G=GL2(C). which means general linear group with each components are complex number.
and let H = {2x2 matrix (a b ; c d) l a,b,c are in Complex number, ac is not zero}
Prove that every element of G is conjugate to some element of the subgroup H and deduce that G is the union of conjugates of H [ Show that every element of GL2(C) has an eigenvector ]

3. Let H be a subgroup of G with |G|/\H = 2. Prove that H is normal in G. Hint: Let G. If Hthen explain why xH is the set of all elements in G not in H. Is the same true for H.C? Remark: The above problem shows that A, is a normal subgroup of the symmetric group S, since S/A, 1 = 2. It also shows that the subgroup Rot of all rotations...

Problem 3. Subgroups of quotient groups. Let G be a group and let H<G be a normal subgroup. Let K be a subgroup of G that contains H. (1) Show that there is a well-defined injective homomorphism i: K/ H G /H given by i(kH) = kH. By abuse of notation, we regard K/H as being the subgroup Imi < G/H consisting of all cosets of the form KH with k EK. (2) Show that every subgroup of G/H is...
