Hi,

I have attached image because I do not know how to type math symbols on this site.

Anyway, I am studying game theory and the topic is transereable utility games in coalitional form.

Note that the professor says, that an additive game is determined by a vector a is element of a set of real numbers to the power of N. I am sure the superscript is to denote the size of vector a, am I right?

I want to know what he means by that expression. Does he mean that "a" is a tuple of size N (N is the number of players in the game) where each element comes from the set of real numbers?

I have looked on wikipedia. Wiki explains the other vectors but not this kinda notation of vectors.

Thanks is advance.
