WebA lattice path P in Z is a path in the d-dimensional integer lattice Z which uses only points of the lattice, that is, it is a sequence (P0, P1, . . . , Pl), where Pi ∈ Z d for all i. The vectors −−→ P0P1, −−→ P1P2, . . . , −−−−→ Pl−1Pl are called the steps of P . The number of steps, l, is called the length of P , and denoted by l(P ). Figure 1 shows a lattice path ...

It is a nice surprise (obtained via the “kernel method”) that the generating functions of the moments of the area are algebraic functions, expressible as symmetric functions in terms of the roots of the kernel.
