Abstract
This short chapter is a brief guide to the background and the topics treated in the book. We begin by recalling the key equations for integrability in two dimensions, motivate a generalization to three dimensions, digest how a class of quantum groups known as quantized coordinate rings play an important role, and mention some fruitful applications.

Notes
- 1.
- 2.
In later sections, \(\mathcal {F}\) is taken slightly differently for L, G, J.
- 3.
The quantized Yang–Baxter equation is well known as a version of the tetrahedron equation. See Sect. 2.7 for a historical note. The quantized reflection equation and the quantized \(G_2\) reflection equation were introduced in [85, 105].

An intrinsic reason why (1.5) admits such a “physical” presentation in terms of scattering diagrams (Figs. 2.18, 4.6 and 8.1) is yet to be revealed.
- 5.
It is parallel with 2D, where the quantum group symmetry of the form \(\mathcal {R}\mathcal {L}\mathcal {L}=\mathcal {L}\mathcal {L}\mathcal {R}\) automatically implies the Yang–Baxter equation \(\mathcal {R}\mathcal {R}\mathcal {R} = \mathcal {R}\mathcal {R}\mathcal {R}\) [43, 63].

- 7.
Such an approach to the tetrahedron equation was first undertaken in [77].

- 9.
For the Yang–Baxter equation, one may say that almost any trigonometric solution should be just the image of the universal \(\mathcal {R}\) in principle (top down). True. However, to describe or construct one in a tractable manner is another problem of individual interest (bottom up). A typical recipe of the latter is the fusion construction. The 3D approach briefed in this section is another having its own intriguing scope.
- 10.
To characterize \(\mathcal {X}(z)\) for \(G_2\) in such a quantum group theoretical framework is an open problem.
