The existence of a resolving system (the local uniformization theorem) was proved for arbitrary varieties over a field of characteristic zero (see [1]), and also for two-dimensional varieties over any field and three-dimensional varieties over an algebraically closed field of characteristic other than 2, 3 or 5 (see [2]).
In the general case the local uniformization theorem implies the existence of a finite resolving system (see [3]).

 Riemann mapping theorem - Wikipedia, the free encyclopedia
The theorem was stated (under the assumption that the boundary of U is piecewise smooth) by Bernhard Riemann in 1851 in his PhD thesis.
The Riemann mapping theorem is the easiest way to prove that any two simply connected domains in the plane are homeomorphic.
The Riemann mapping theorem can be generalized to the context of Riemann surfaces: If U is a simply-connected open subset of a Riemann surface, then U is biholomorphic to one of the following: the Riemann sphere, the complex plane or the open unit disk.

 Riemann Mapping Theorem | World of Mathematics
One of the central results in the subject of complex analysis, the Riemann mapping theorem unifies the areas of algebra, geometry, and topology.
The "uniformization theorem" says that any closed surface with no boundary has one of only three types of conformal geometry.
The absence of other possibilities stems directly from the Riemann mapping theorem, because the geometry of the surface is first "lifted" to a planar covering space and then mapped by Riemann's theorem to the unit disk.

 The aim of uniformization   (Site not responding. Last check: 2007-09-12)
The uniformization theorem in two dimensions is a very powerful result, for both differential geometry and topology.
The theorem has not been proved yet, but there are no counterexamples, and a large number of proofs for special cases.
What is important here is that this flow generalizes to three dimensions such that the fixed points of the flow are the eight homogeneous geometries plus certain ``instanton" configurations, which describe ``necks" between three-manifolds.

The subject of study is uniformization theorems in differential geometry.
In particular, we're using a proposition by Jack and Eric (to be detailed later), that uses BF field theory as a method of `flowing' the geometry of a manifold to a homogeneous one.
In two dimensions, this leads to the well-known uniformization theorem, ie that all compact orientable Riemann surfaces are just distortions of homogeneous surfaces with n handles.

 TEICHMÜLLERTHEORY
It was Teichmüller who realized that introducing a new relation, based on quasiconformal mappings (and some homotopy conditions) one gets a space, known as the Teichmüller space, which is simpler to study than the Riemann space.
This new space is the universal covering space of Riemann space; the mapping class group (see Nielsen's theorem 1.33) becomes the covering group.
Thus one reduces the study of Riemann space to the study of Teichmüller space and the mapping class group.

Working with functions of p-adic numbers is sort of halfway in between algebra and analysis, so the idea is that studying p-adic problems might provide insights into why the existence of many rational solutions to equations seems to be related to the existence functional solutions.
Another area Cherry works in is known as Nevanlinna theory, which extends the Fundamental Theorem of Algebra to meromorphic functions.
Finally, Cherry continues to have research interests in classical complex analysis, particularly the use of geometric methods to better understand various inequalities.
