Reduced distribution function
Definition
| $ \rho $ … Classical probability density function |
| $ N \equiv \mathrm{dim}(\mathcal M) $ |
| $f_s(q^1,p_1,q^2,p_2,\dots,q^s,p_s):=\int\ \rho\ \ \mathrm d q^{s+1} \mathrm d p_{s+1}\cdots \mathrm d q^N \mathrm d p_N$ |
Discussion
We also set $f_N:=\rho$, but that's just introduction of different notation.
Relevant for discussions of kinetics on the intermediate level $f_1$ and $f_2$. And maybe $f_3$ if you're mad enough.
