(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What does this notation mean?I understandthe $$\{x_t\}_{t = 0}^{\infty}$$ part, but I don't know what exactly $$U(x_0, x_1, ... x_n)$$ means. Does it mean that this function is a n+1 dimensional function, the same way f(x, y) is a 3 dimensional function?

2. Relevant equations

$$U(\{x_t\}_{t = 0}^{\infty}) = U(x_0, x_1, x_2, ... x_n)$$

3. The attempt at a solution

Tried Googling without any luck.
