It seems to me that to study mathematics is to convert the abstract language into diagrams, graphs and images. It does depend on the subject how much this technique can ease the struggle yet most of the time it is helpful, at least to some extent.
However, studying operator algebras and related fields, I find hardly any images or diagrams can be drawn which makes this subject particularly difficult for me.
I checked almost every book I can find yet none of them contains any technique for visualization.
I wonder whether someone here have advice or experience on visualizing operator algebras. Even just simple diagrams may be helpful.
