Every group is a normal subgroup of itself. Similarly, the trivial group is a subgroup of every group.
WebDec 21, 2024 · We prove that if a group is abelian then every subgroup of it is normal. We prove in a later video that the converse of this theorem is not true in general. We also find … WebThe x-axis and the y-axis are each subgroups but their union is not. For instance (1, 0) is on the y-axis and (0, 1) is on the x-axis, but their sum (1, 1) is on neither. So the union of the two axes is not closed under the group operation and so it’s not a …
