Wtf is that nonsense? lol

What nonsense is this? It's abstract nonsense!



Hey, Mphlee. I absolutely agree with you, but I think you misread me. I write,

\( f\bullet g \bullet z \)

To make it distinct. Which inherently also means \( f \circ g \circ z \) as you say it. I was mostly just making an argument against using \( \circ \). Whereas, someone sees that with circ and thinks it an abuse of notation; whereas with a bullet, itis given this meaning. On top of that, now we can look at, a sequence of forms (don't worry, I don't use forms, it's mostly just a comparison of notation) \( f_j \bullet g_j \bullet z \) and we can attach an operator/functor to them, \( \Omega_j \). I just really don't like the use of \( \circ \) notationally/typographically. I believe it would warrant confusion. But I'm so happy that you see the categorical structure. Again, I had help by someone really smart in designing this notation...<_<

EDIT: Oh and I look forward to reading the PDF!

I was also suggested \( f \leftarrow g \leftarrow z \) but it was agreed bullet is much better. This one is a bit toooo categorical, If you know what I mean.

Edit2:

\(
ds \leftarrow z\\
\)

looks fucking awful, eh?
