This paper is the first part of a cycle of three articles, which is a survey devoted
to the discussion of problems of the unique determination of conformal type for domains
in Euclidean spaces. The main goal of the survey is to present a new apparently, very
interesting and yet very difficult trend in the classical geometric topic of the unique
determination of convex
surfaces by their intrinsic metrics. This (the first) article of the cycle relies upon
the author's talk “Unique Determination of Polyhedral Domains and $p$-Moduli
of Path Families” given at the International Conference “Metric Geometry of Surfaces and
Polyhedra” (Moscow, August 2010) dedicated to the 100th anniversary of Prof. N. V. Efimov,
and the article itself is an extended version of this talk.
Note that the author developed problems of the unique determination of conformal type
for domains in Euclidean spaces in earlier papers. In the present article,
we expose new results on the problem of the unique determination of conformal type
for domains in $\mathbb R^n$.
In particular, we show that a (generally speaking) nonconvex bounded polyhedral domain in
$\mathbb R^n$ ($n \ge 4$)
whose boundary is an
connected manifold of class
without boundary and is representable as a finite union of pairwise nonoverlapping
cells is uniquely determined by the relative conformal moduli of its boundary condensers.
Results on the unique determination (of polyhedral domains) of isometric type are also obtained.
In contrast to the classical case, these results present a new approach in which the notion of the
$p$-modulus of path families is used.
