We show in one A3 sheet [1-5] and/or more substantially [6,7] how the
soliton, first reported by J. S. Russell in August 1834, has come to
occupy, in 1995, a central position in the theory of 2-dimensional
quantum gravity. This `A3 sheet' is reproduced here as A4 pages to
make it easy to print out, click on
LHS and
RHS respectively.

- The `map' called `Solitons', which is the `A3 sheet'
referred to, is submitted to the publishers (World Scientific) in A3
form but the printed form is to be decided. Copies in A3 size are
available from the authors however. This `map' is introduced in
§ 5 of [1] and some brief interpretative discussion of it is
given there [3].
- See also the several references concerning this `map' (e.g. the Refs
100, 17, 101, 102, 82 and 83) in [1].

available from the authors. A correction to [6] will be published
in Acta Applicandae Mathematicae in due course.
- Two-dimensional quantum gravity is handled explicitly in of
[6,7]. The connection derived by Gross and Migdal [6,7,9] and
others [6,7] between the functional integral due to Polyakov and the
matrix models, and the connection between the one-matrix model and
the stationary flows of the whole KdV (Korteweg-de-Vries)
hierarchy as equations for the kth `multi-critical point' for
the `specific heat' [6,7,9] is given in this §6. The connection
between this result and the KP (Kadomtsev-Petviashvili) hierarchy,
as well as the KdV hierarchy, via the Weyl
algebra as
expressed on the `map' is also established in this [10].
