Stochastic kinematic description of a complex dynamics is shown to dictate an energetic and thermodynamic structure. An energy function ##IMG## [http://ej.iop.org/images/0295-5075/131/5/50002/epl20266ieqn1.gif] {$\varphi(\textbf{x})$} emerges as the limit of the generalized, nonequilibrium free energy of a Markovian dynamics with vanishing fluctuations. In terms of the ∇ φ and its orthogonal field ##IMG## [http://ej.iop.org/images/0295-5075/131/5/50002/epl20266ieqn2.gif] {${\boldsymbol{\gamma}}(\textbf{x})\perp\nabla\varphi$} , a general vector field ##IMG## [http://ej.iop.org/images/0295-5075/131/5/50002/epl20266ieqn3.gif] {$\textbf{b}(\textbf{x})$} can be decomposed into ##IMG## [http://ej.iop.org/images/0295-5075/131/5/50002/epl20266ieqn4.gif] {$-\textbf{D}(\textbf{x})\nabla\varphi+{\boldsymbol{\gamma}}$} , where ##IMG## {$\nabla\cdot(\omega(\textbf{x}){\boldsymbol{...}
