>>14241779You're sending an out of context image which can represent anything. Though, to me, it looks like tensor products, pull back functions, maybe a folium/leaf thing (the delta v, lambda). Then the arrows represent mappings, functors, or a communative diagram.
Really though, it could mean anything depending on the field. I've seen notation used in diff geo, also in algebra, and they mean different things though they are the exact same, notation wise.
Also, specialization. As mathematicians specialize, they are unfamiliar with other fields/terminology.
But, like:
>>14241817I agree. /sci/ might not be as good. I joined when it was already tardery about IQ and shit. I only have a faint idea of how good it was by mentors of mine telling me abt their experience awhile back.
