  Topology   (Site not responding. Last check: 2007-10-14)
Topology is the mathematical study of those properties that are preserved through continuous deformations of objects.
A circle is topologically equivalent to an ellipse, a sphere is equivalent to a cube, and a coffee cup to a donut.
Geometric topology is the study of manifolds and their embeddings, with representative topics being knot theory and braid groups.

 Topology - Wikipedia, the free encyclopedia
Topology (Greek topos, place and logos, study) is a branch of mathematics concerned with spatial properties preserved under bicontinuous deformation (stretching without tearing or gluing); these are the topological invariants.
Topology has sometimes been called rubber-sheet geometry, because it does not distinguish between a circle and a square (a circle made out of a rubber band can be stretched into a square) but does distinguish between a circle and a figure eight (you cannot stretch a figure eight into a circle without tearing).
In pointless topology one considers instead the lattice of open sets as the basic notion of the theory, while Grothendieck topologies are certain structures defined on arbitrary categories which allow the definition of sheaves on those categories, and with that the definition of quite general cohomology theories.

Perhaps the single most interesting problem in low dimensional topology is to determine to what extent group invariants characterize a manifold.

 Geometric topology - Wikipedia, the free encyclopedia
In mathematics, geometric topology is the study of manifolds and their embeddings, with representative topics being knot theory and braid groups.
In the rapid development of topology after 1945, a distinction was drawn between the fields of algebraic topology typified by homotopy theory, geometric topology with the Poincaré conjecture as its biggest unsolved problem, and differential topology as the study mostly of differential structures, with Morse theory and transversality as their natural techniques.
Thurston's geometrization conjecture, formulated in the late 1970s, offered a framework that suggested geometry and topology were closely intertwined in low dimensions, and Thurston's proof of geometrization for Haken manifolds utilized a variety of tools from previously only weakly linked areas of mathematics.

 Conference on Low-Dimensional Topology   (Site not responding. Last check: 2007-10-14)
The objective of the conference is to bring together researchers working on different aspects of low-dimensional topology, including Floer homology, the Ricci flow program, and more "classical" geometric topology, with the goal of looking for connections and unifying perspectives.
A theme in several of these areas is that subtle relationships between a 4-manifold and its boundary constrain and illuminate both 3- and 4-dimensional topology.
We propose this as a framework for comparing existing approaches and formulating key problems.

 Hopf algebras, quantization and low-dimensional topology   (Site not responding. Last check: 2007-10-14)
at the beginning of the nineties are at the origin of unexpected but extremely fruitful interactions between Hopf algebras, quantum groups and low-dimensional topology.
During this meeting, we will study certain aspects of the spectacular results of these interactions, in particular, an intrinsic approach to quantum groups, Kazhdan-Etingof's biquantization theory and integrality properties in the theory of invariants in low-dimensional topology.
In several talks, we will also touch on the new combinatorial theory of Hopf algebras, which has its origin in the works by Connes-Kreimer on renormalization.

Current research areas on which the conference will focus include gauge theory and smooth structures on 4-manifolds, symplectic and contact topology, topology of 4-manifolds, quantum topology and perturbative invariants of knots and 3-manifolds, hyperbolic geometry in dimension 3, and combinatorial methods in knot theory and 3-dimensional topology.
Such areas might include gauge theory, smooth and topological structures on 4-manifolds, symplectic and contact topology, invariants of knots and 3-manifolds, 3-dimensional hyperbolic goemetry, and normal surface theory.
We are also hoping to have a few talks of a historical nature, aimed at a broad audience, and reviewing the breakthroughs in the sixties and seventies which paved the way for the modern theory of manifolds.

Low-dimensional topology usually deals with objects that are two-, three-, or four-dimensional in nature.
This fact is particularly noticeable in dimensions three and four, and so alternative specialized methods have evolved.

The study of 3-manifolds through their fundamental groups and symmetries has turned out to be a particularly rich vein withapplications to such topics as the tabulation of knots, geometrization problems, group actions, and surgery theory.
Recently there have been important break throughs in the study of the topology of manifolds and related topics on group actions, especially in the area of 3- and 4- dimensional manifolds with new imput from the Seiberg-Witten theory and symplectic topology.
