Notably, a series of investigations have employed exact field-theoretical methods to derive analytic expressions for one- and two-point correlation functions in systems at phase coexistence.

Study of the cross-correlation functions can indicate the transfer functions through which the input series should enter the model for the response series. The cross-correlation function is computed ...

The pair correlation function is a fundamental spatial point process characteristic that, given the intensity function, determines second order moments of the point process. Non-parametric estimation ...

Calculations are reported here of the structure factor S (k) and the direct correlation function C (k) = 1-S-1 for a classical hard sphere fluid. Exact results are presented to order of the cube in ...
