Or fancy letters, like the L in a Laplace transformation.

And if that's not enough, you just straight up make up new symbols, like Nabla

Ah yes, because other science fields like linguistics would never just grab random letters and turn them upside down to repurpose them!

Any upsidedown A in the set of all real characters used in academia would immediately illicit mathematical memories.

Did you mean ALL the upside up A?

[–] Poik@pawb.social 2 points 2 months ago (1 children)

I usually used it as "for all", but its looks like "for any" is used too

[–] Poik@pawb.social 1 points 2 months ago

I sit corrected. It's used as an arbitrary singular value within the proof, so for any always felt more appropriate.
