Can anyone explain why a freely indecomposable group is important or handy?
I can't seem to understand the definition. It says that a group G is free indecomposable if
[tex]G = A \star B \Rightarrow G = A \vee G = B[/tex]
So is it really saying that a free product A * B is freely indecomposable if
[tex]A \star B \Rightarrow A \star B = A \vee A \star B = B[/tex]?
