| Aug 23, 2012 at 15:53 | comment | added | Arturo Magidin | On another tack, in trying to characterize the capable $p$-groups of exponent $p$ and class $2$, I ended up looking at certain morphisms between the commutator subgroups of the relatively free groups of exponent $p$ and class 2 and those of exponent $p$ and class $3$. I then interpreted them as linear maps between vector spaces, and worked in the linear algebra setting instead (because I found it more easy to think about). Some of that stuff is in the arXiv: front.math.ucdavis.edu/0506.5578. | |
| Aug 23, 2012 at 15:50 | comment | added | Arturo Magidin | Not very deep, but the proof that a group that has only the identity automorphism must be $C_2$ uses this fact (together with the Axiom of Choice to construct of a basis). | |
