Hi,
I am trying to understand the meaning of “pc_gamg_square_graph”. I did not find a specific reference to “square” in the tutorial here: http://user.it.uu.se/~maya/Projects/3phase/AMG_parallel_Falgout.pdf <http://user.it.uu.se/~maya/Projects/3phase/AMG_parallel_Falgout.pdf> .
What would be a good place to look for some background on this?
Regards,
Manav
