Potpourri Seminar 2 p.m. Thursdays Link to Zoom
Revival of the seminar!
A general chat + a possible talk:
Jerzy Kocik
On a certain discrete matrix group
Hello, can you post the "N" matrix described here, or the variable. I am having trouble because I remembered it as the permutation of the Apollonian Matrices, but they were represented differently than the form I have them here:$\begin{bmatrix}0 & & & 1\\& 1 & & \\& & 1 & \\-1 & 2 & 2 & 2\end{bmatrix}$
*video (not variable) and *transpose (not permutation)(You cannot edit your comments here :-) )
Thanks, Derek. The video is now on.
