Statistical Mechanics is a well grounded probabilistic theory, which can be explained by means of a fundamental principle, the principle of maximum entropy, where through this theory the laws ruling thermodynamics can be deduced. On the contrary, Non-equilibrium Statistical Mechanics lacks an axiomatic foundation or even a unified formulation; rather, it consists of a set of theorems and relations of particular validity (for example in stationary situations) without a clear connecting thread. The only common element to all these fragments is the use of time-dependent probabilities and expectations, typically related by means of partial differential equations or general validity relations.
Given the above, it would be of vital interest to be able to establish a principle that allows us to deduce the current structure of the partial theories of Non-equilibrium Statistical Mechanics, analogously to how the structure of Equilibrium Statistical Mechanics is deduced from the principle of maximum entropy.
This thesis will show how through the principle of Maximum Caliber (or Maximum Path Entropy) and what we will call inference over paths, it’s possible to derive and fully relate these elements that make up the Non-equilibrium Statistical Mechanics, establishing a systematic and orderly method to understand the origin of the differential relations and equations that compouse this theory. This is a first approach to a theory that allows us to understand the Non-equilibrium thermodynamics.
