Infinitely-Precise Space-Time Discretizations of the Equation ut + uux = 0, of the Volterra system is preserved exactly. Since in the space-continuous limit the Volterra system turns into the basic nonlinear infinite-dimensional dynamical system .. + .. = 0, the Volterra conservation laws are discretizations of the conservation laws (../.). + [(../(.+1)] . = 0, . ∈ ..

Mullikottu-Veettil Mukundan,Mark Brayphic behaviour. In the simplest case, this correspondence is as follows. Let Γ be a discrete subgroup of ..(ℝ) acting on the complex upper half-plane . in the usual way, and . a modular form of even weight . on Γ. Then there is a unique lifting from . to a Γ-invariant ΨDO with leading term .∂., wher
