Is there a standard notation for the product from right to left?

Question

I am considering a product of the matrices $(A_i)_{1\leq i\leq n}$ in reverse order $$P=A_nA_{n-1}\dots A_1,$$ and I was wondering if there was a standard notation for it, like $\overleftarrow{\prod}$ or $\prod^R$... Thanks

Answer 1

I don't think there is such a notation.

However, you won't need it, as you can do the following product:

$$\prod_{i=1}^n A_{n-i+1}$$

or equivalently

$$\prod_{i=0}^{n-1} A_{n-i}$$
