2d	accepted	Is there a name for this given type of matrix?
2d	comment	Is there a name for this given type of matrix? Thanks for that.
2d	comment	Is there a name for this given type of matrix? @SammyBlack Thanks for the response. Just to clarify though, I was not thinking of giving a name to such matrices. Rather, I was trying to ascertain if such matrices had already been named and what research had been undertaken on them already.

2d	comment	A normal subgroup intersects the center of the $p$-group nontrivially There is a nice generalisation of this result. If $G$ is a nilpotent group and $1\neq H\unlhd G$, then $H\cap Z(G)\neq 1$. Since all $p$-groups are nilpotent, your result could be seen as a corollary of this (if you want a different way of looking at things that is).

Apr 19	comment	Computing singular homology This is a question from a take-home exam which is in-progress. I kindly ask that all well-meaning respondents wait until Saturday April 27th to answer this question.

Apr 19	comment	Computing singular homology You really shouldn't just post virtually all of a coursework assignment on a forum. People don't have any problem trying to help you with the understanding of a subject, but just posting the questions here is only likely to infuriate people.
