We prove a large deviation principle on path space for a class of discrete time Markov processes whose state space is the intersection of a regular domain Λ ⊂ ℝd with some lattice of spacing ∈. Transitions from x to y are allowed if ∈-1(x-y) ∈ Δ for some fixed set of vectors Δ. The transition probabilities p(t,x,y), which themselves depend on ∈, are allowed to depend on the starting point x and the time t in a sufficiently regular way, except near the boundaries, where some singular behaviour is allowed. The rate function is identified as an action functional which is given as the integral of a Lagrange function. Markov processes of this type arise in the study of mean field dynamics of disordered mean field models.
