141. Topology Of Manifolds And Homotopy Theory with the participation of, with the particpation of MITACS. Topology of manifolds and Homotopy Theory. March 20 25, 2004. Organizers http://www.pims.math.ca/birs/workshops/2004/04w5533/

with the participation of Topology of Manifolds and Homotopy Theory March 20 - 25, 2004 Organizers: Ian Hambleton (McMaster University), Erik Pedersen (SUNY Binghamton), Gunnar Carlsson (Stanford University). Objectives The purpose of this meeting is to bring together researchers in a wide variety of areas in algebraic and geometric topology, to investigate problems of current interest, and to make new connections. In particular, we believe the time is ripe for a productive exchange of ideas and viewpoints among mathematicians in active areas of homotopy theory and the topology of manifolds, in the hope of enriching the future development of both subjects. The actual topics of the meeting will be determined by the participants. Here are some of their research interests: (1) "Structured homotopy theory", meaning homotopy theory on the category of modules over a ring spectrum, (2) Controlled and equivariant surgery, (3) Conjectures of Baum-Connes and Novikov on assembly maps in K-theory and L-theory. (4) New product structures on the homology of the free loop space of a manifold, moduli spaces

149. BoatUS BoatTECH Guides: Exhaust Manifolds Exhaust manifolds. Exhaust manifolds last forever, don t they? Even parts. manifolds and risers live in an incredibly harsh environment. http://www.boatus.com/boattech/exh.htm

Exhaust Manifolds Exhaust manifolds last forever, don't they? Even if they do fail, it isn't a major problem, right? These are common reactions when people are asked about their boat's manifold. Unfortunately, exhaust manifolds are important, and ignoring them can potentially lead to expensive problems, perhaps an engine rebuild. There is an additional hassle-manifolds are normally damaged by corrosion, so they're not covered by your insurance policy. All of this makes the outlook seem rather bleak. It's not as bad as it seems, though. All that's needed is a change in attitude. Rather than seeing it as a "sealed for life" component, view a manifold as a service item to be replaced at regular intervals. If you do this, major problems can be avoided. Life Expectancy How long will a manifold last? Obviously the way you use your boat will be a factor, as will the type of water it's on. Saltwater boats are going to see a shorter manifold life when compared to their freshwater counterparts. Most experts suggest that a manifold will have a life expectancy of six to eight years. However, heavy use in saltwater can see this drop to as low as three years, while lightly used freshwater boats can get up to 20 years out of a manifold. One thing is for certain, the older your manifold gets, the more likely it is to fail. This is clearly shown in the chart below.

Advanced Course on Geometric 3-Manifolds A Euro Summer School List of registered participants Programme Dates: September 12 to 20, 2002 Place: Centre de Recerca Matemàtica Campus of the Universitat Autònoma de Barcelona, Bellaterra Coordinator: Joan Porti (UAB) Speakers: Michel Boileau (Université Paul Sabatier) Geometrization of 3-manifolds with symmetry Summary: The goal of these lectures is to present a proof that a closed, orientable, irreducidble and atoroidal 3-manifold which admits a non-trivial, orientation preserving, non-free symmetry of finite order, admits either an elliptic or hyperbolic metric. Cyclic branched covering along knots or links in S are examples of such manifolds. First we will recall basic facts in 3-dimensional topology and then introduce the main tools needed for the proof. We will use results from the lectures of Leeb and Otal. Bernhard Leeb (Universität Tübingen) The geometry of cone manifolds and the Orbifold Theorem Summary: Cone manifolds are singular metric spaces with curvature bounded below and with sigularities of a very restricted type. They play a central role in the geometrization of orbifolds. We will discuss basic geometric results concerning their small-scale structure and possible degenerations, and explain how they are used in the proof of the Orbifolds Theorem.

Geometry and Topology Monographs Volume 5: Four-Manifolds, Geometries and Knots Jonathan Hillman This book arose out of two earlier books 2-Knots and their Groups and The Algebraic Characterization of Geometric 4-Manifolds , published by Cambridge University Press for the Australian Mathematical Society and for the London Mathematical Society, respectively. About a quarter of the present text has been taken from these books, and I thank Cambridge University Press for their permission to use this material . The arguments have been improved and the results strengthened, notably in using Bowditch's homological criterion for virtual surface groups to streamline the results on surface bundles, using L^2 methods instead of localization, completing the characterization of mapping tori, relaxing the hypotheses on torsion or on abelian normal subgroups in the fundamental group and in deriving the results on 2-knot groups from the work on 4-manifolds. The main tools used are cohomology of groups, equivariant Poincare duality and (to a lesser extent) L^2-cohomology, 3-manifold theory and surgery.

We show that an essential lamination in a Seifert-fibered space M always contains a sublamination which can be made either `horizontal' or `vertical' with respect to the foliation of M by circles. As a consequence, we find the first (and, to date, only) examples of 3-manifolds with universal cover R^3 which do not contain any essential laminations.

Geometry and Topology Monographs Volume 4: Invariants of knots and 3-manifolds (Kyoto 2001) T Ohtsuki, T Kohno, T Le, J Murakami, J Roberts and V Turaev (editors) Preface The workshop and seminars on "Invariants of Knots and 3-Manifolds" took place at the Research Institute for Mathematical Sciences (RIMS), Kyoto University, in September 2001. The workshop was held over the period September 17-21. Seminars were held on the Tuesdays, Wednesdays and Thursdays of the other weeks of September, including "Goussarov day" on September 25. Since the interaction between geometry and mathematical physics in the 1980s, many invariants of knots and 3-manifolds have been discovered and studied: polynomial invariants such as the Jones polynomial, Vassiliev invariants, the Kontsevich invariant of knots, quantum and perturbative invariants, the LMO invariant and finite type invariants of 3-manifolds. The discovery and analysis of the enormous number of these invariants yielded a new area: the study of invariants of knots and 3-manifolds (from another viewpoint, the study of the sets of knots and 3-manifolds). There are also developing topics related to other areas such as hyperbolic geometry via the volume conjecture and the theory of operator algebras via invariants arising from 6j-symbols. On the other hand, recent works have almost completed the topological reconstruction of the invariants derived from the Chern-Simons field theory. An aim of the workshop and seminars was to discuss future directions for this area. To discuss these matters fully, we planned 1 month of activities, relatively longer than usual. Further, to encourage discussions among the participants, we arranged a short problem session after each talk, and requested the speaker to give his/her open problems there. Many interesting problems were presented in these problem sessions and, based on them, we had valuable discussions in and between seminars and the workshop. Open problems discussed there were edited and formed into a problem list, which, I hope, will clarify the present frontier of this area and assist readers when considering future directions.
