If we have a many-body sistem and we study the limit with infinite particles (we may decide for example to have a fixed constant density), I am trying to understand how classical mechanics and quantum mechanics justify, from both a mathematical and a physical point of view, the existence of the total momentum defined as $\lim_{N \to + \infty} \sum_{i = 1}^{N} p_i$ , where $p_i$ is the momentum (l…
