This board sucks, lets talk about math and scientific concepts we enjoy/find interesting.
I love this lil nigga like you wouldn't believe

>Doesn't care to explain how this coincides with viewing vector space complexification as the tensor product of C with said vector space
>Doesn't care to explain how this coincides with taking the fucking tensor product of the tangent space with the cotangent space and what the fuck that means intuitively without bringing in category theory garbage that just obfuscates the matter
>oh lol it's just the kronecker product
For fuck sakes

Undefined is my man. I mean, just look at these goofy fucks:

$\frac{n}{0}$

$\log_0 (n)$ , $\log_n (0)$ , $\log_1 (n)$

$\infty - \infty$

Learn category theory. Tensor product is just the action of the monoidal bifunctor.

Draw a fucking picture of the tensor product of two vectors in R2 and let's see how good your definition holds up

I always found this one silly
