During this booklet, Professor Novikov describes contemporary advancements in soliton thought and their family members to so-called Poisson geometry. This formalism, that is relating to symplectic geometry, is very valuable for the research of integrable structures which are defined by way of differential equations (ordinary or partial) and quantum box theories.

We consider a path in Q to be a (finite or infinite) sequence of arrows (an ) such that han = tan+1 . We will call a path simple if it contains no repeated arrows. We will also consider ‘unoriented’ paths, where we do not have to respect the orientation of the arrows. These can be considered as paths in the doubled quiver and where we denote the opposite arrow to a by a−1 . We call an unoriented path simple if it contains no arrow which is repeated with either orientation. 3. We note that the support of a simple path does not have to be a simple curve in the usual sense, and may intersect itself as long as the intersections occur at vertices.

20, like perfect matchings, are functions which evaluate to one on each arrow in their support. Therefore they can be thought of as sets of arrows. We now show that P (σ) is non-zero on the zigs or zags of certain zig-zag paths, in other words that these zigs or zags are contained in the set of arrows on which P (σ) is supported. In the language of functions, this is equivalent to the following lemma. 22. Suppose σ is a cone in the global zig-zag fan Ξ spanned by rays γ + and γ − (see diagram below).

The global zig-zag fan Ξ in H1 (Q) ⊗Z R, is the fan whose rays are generated by the homology classes corresponding to all the zig-zag flows on Q. This is a refinement of each of the local zig-zag fans and is therefore a well defined fan. 18. We illustrate with an example which we shall return to later in the chapter. Consider the following dimer model and corresponding quiver drawn together as before. The dotted line again marks a fundamental domain. In this example there are five zig-zag paths, which we label η1 , .
