What does the $\prod$ symbol mean? - Mathematics Stack …
WEB1. For example, 3 ∏ i = 0ai = a0 ⋅ a1 ⋅ a2 ⋅ a3. This is a symbol for product similarly as ∑ for sum. Your use of the × symbol begs the question, if the products are vectors is the pi-product scalar or vector? (cross or dot product) If it is not vector, then the ⋅ symbol would be more appropriate.

WEBA A and B B are compact metric spaces. μ μ and ν ν are probability distribution over A A and B B, resp. Φ Φ is a continuous function A × B → R A × B → R. Φ~(μ, ν) Φ ~ (μ, ν) is said to be the expected value of Φ Φ. I understand that you need to integrate over A × B A × B to get this expected value, and to take μ μ and ν ...

WEBis a vector and element-wise multiplication is a natural thing to want to do. While in the above example I could avoid the problem by writing xk = ikΔk + bk x k = i k Δ k + b k. , having a symbol for element-wise multiplication lets us mix and match matrix multiplies and elementwise multiplies, for example y = A(i ⊙ Δ) + b y = A (i ⊙ Δ ...

WEB$\begingroup$ since vector multiplication is overloaded quite a lot as is, you can't trust that any arbitrary reader will understand your notation; to avoid this problem, use any symbol you want as long as you leave a "let denote pairwise multiplication of vectors" before using it or "where denotes pairwise multiplication" after using it, and make sure that you only …
What does a dot in a circle mean? - Mathematics Stack Exchange

WEBAug 5, 2021 · 0. This is a perfectly fine way of writing this product and it is used quite frequently - but definitely a little bit less frequently than the sum-symbol. The only caveat (for both) is that it should be clear that this product makes sense: This is surely the case if X X is finite. It will be a lot trickier if X X is not finite, as (just as with ...
Differentiating a product symbol - Mathematics Stack Exchange
WEB1. Can someone explain how to differentiate something like. ∏i<jN (xi −xj) ∏ i <j N (x i − x j) with respect to xi x i. The product starts from 1 and goes to N. I started off by ignoring the xj x j as it doesn't depend on i i but I have a feeling that's not correct. What confuses me is the i <j i <j. I have tried this on Maple but the ...
How to Make a Math Symbol in Word - Mathematics Stack Exchange
WEBIt does seem that Word will render the symbol by "copy and paste". It worked in implementation of Word (Office 10), and rendered as Cambria Math (font), with size $13$, which can be scaled to a different font size. Edit: the symbol "$\boxtimes$" can be directly inserted from/within "Word" using: "insert":
