ABSTRACT: In 1997, T. Cochran, K. Orr, and P. Teichner defined a
filtration
of the classical knot concordance group. The filtration is defined in
terms
of gropes or Whitney towers and is connected to the classification of
topological 4-manifolds. We will discuss some joint work with Tim
Cochran
and Shelly Harvey that establishes explicit families of knots that
generate
infinite rank subgroups of each filtration quotient.

TITLE: Atiyah-Meyer formulae for Hodge-type invariants of algebraic
varieties.
ABSTRACT: I will report on recent progress on the study of genera and
characteristic classes of algebraic varieties. I will describe
Hodge-theoretic analogues of the Atiyah-Meyer signature formula, and
discuss possible extensions of these results to the singular
setting. This
is joint work with S. Cappell, A. Libgober and J. Shaneson.

Title: Loop products and closed geodesics
Abstract: The critical points of the energy function on the free
loop space L(M)
of a compact Riemannian manifold M are the closed geodesics on M.
Filtration by the length function gives a link between the geometry of
closed geodesics and the algebraic structure given by the
Chas-Sullivan
product on the homology of L(M). Geometry reveals the existence of a
related product on the cohomology of L(M). For manifolds such as
spheres
and projective spaces for which there is a metric with all geodesics
closed, the resulting homology and cohomology rings are nontrivial,
and
closely linked to the geometry. I will not assume any knowledge of
the
Chas-Sullivan product. Joint work with Mark Goresky.

Title: From invariant theory to homotopy groups.
Abstract:
We determine the v1-periodic homotopy groups of all
irreducible p-compact groups (BX,X). In the most difficult,
modular, cases, we follow a direct path from their associated
invariant polynomials to these homotopy groups. We show that, if p
is odd, every irreducible p-compact group has X of the homotopy
type of a product of explicit spaces related to p-completed Lie
groups.
Title: Bundle structures and Algebraic K-theory
Abstract:
This talk will describe algebraic K-theoretic
obstructions to lifting fibrations to fiber bundles having compact
smooth/topological manifold fibers. The surprise will be that a
lift can often be found in the topological case. Examples will be
given realizing the obstructions.
Title: Topological complexity of lens spaces
Abstract:
The topological complexity of lens spaces can be
used to approach the immersion problem for odd dimensional
projective spaces. Following work of Fadell-Husseini (1992) and
Farber-Grant (2007), I will describe how to compute the initial
stages in such an approach.
Title: "Stable decompositions of complements of complex coordinate subspace arrangements and generalized moment angle complexes"
Abstract: A report of joint work with Martin Bendersky, Fred Cohen and Sam
Gitler. We investigate a splitting, after one suspension, of a generalized moment
angle complex into pieces related directly to the underlying simplicial complex
defining it. In the particular case of the complements of complex coordinate subspace
arrangements, our result implies a well known homology result of Goresky and
MacPherson.

Title: Derived functors of the locally finite functor
Abstract: Define the functor G from A-modules to A-modules to be the
locally finite functor where G(M) = {m in M | Am is finitely generated
as a vector space}. We describe our interest in this functor and discuss
the specific case when A is an exterior algebra over Z_2 with a countably
infinite number of generators.

Title: Holomorphic disks and invariants for 3-manifolds and smooth
4-manifolds
Abstract: We will introduce and study topological invariants for
closed 3 manifolds and smooth 4-manifolds. The 3-manifold
constructions uses Heegaard diagrams and a version of Langrangian
FLoer homology. The 4-manifold invariant uses the previous
construction, a pairing on FLoer-homology and a handle decomposition
of the 4 manifold. We will also present some applications in three
and 4-manifold topology. This is a joint result with Peter
Ozsvath.
