SUMMARY:Noncommutative Geometry Seminar - Noncommutative Geometry 101: Oper
ators and symbols
DESCRIPTION:Seminar: Noncommutative Geometry Seminar\nTitle: Noncommutative
Geometry 101: Operators and symbols\nSpeaker: Nigel Higson\, Penn State\n
Abstract: I shall give two lectures introducing some of the ideas that app
ear in the research of Penn State's noncommutative geometry group. In the
first I shall discuss differential and Hilbert space operators\, and vari
ous sorts of "symbols" that can be attached to them. In the second I shal
l examine how the general theory applies to Sturm-Liouville operators on a
half-line\, following some remarkable early work Hermann Weyl that has pr
oved to be very influential in representation theory.

SUMMARY:Noncommutative Geometry Seminar - There and back again: from the Bo
rsuk-Ulam Theorem to quantum spaces
DESCRIPTION:Seminar: Noncommutative Geometry Seminar\nTitle: There and back
again: from the Borsuk-Ulam Theorem to quantum spaces\nSpeaker: Piotr M H
ajac\, IMPAN\nAbstract: Assuming that both temperature and pressure are co
ntinuous functions\, we can conclude that there are always two antipodal p
oints on Earth with exactly the same pressure and temperature. This is the
two-dimensional version of the celebrated Borsuk-Ulam Theorem which state
s that for any continuous map from the n-dimensional sphere to n-dimension
al real Euclidean space there is always a pair of antipodal points on the
sphere that are identified by the map. Our quest to unravel topological my
steries in the Middle Earth of quantum spaces will begin with gentle prepa
rations in the Shire of elementary topology. Then\, after riding swiftly t
hrough the Rohan of C*-algebras and Gelfand-Naimark Theorems and carefully
avoiding the Mordor of incomprehensible technicalities\, we shall arrive
in the Gondor of compact quantum groups acting on unital C*-algebras. It i
s therein that the generalized Borsuk-Ulam-type statements dwell waiting t
o be proven or disproven. Time permitting\, we shall pay tribute to the an
cient quantum group SUq(2)\, and show how the proven nontrivializability o
f the SUq(2)-principal instanton bundle is a special case of two different
noncommutative Borsuk-Ulam-type conjectures. (Based on joint work with Pa
ul F. Baum and Ludwik Dabrowski.)

SUMMARY:Noncommutative Geometry Seminar - The amount of torsion in a group
and the degree of non-rigidity of a manifold
DESCRIPTION:Seminar: Noncommutative Geometry Seminar\nTitle: The amount of
torsion in a group and the degree of non-rigidity of a manifold\nSpeaker:
Guoliang Yu\, Texas A & M\nAbstract: I will discuss how to use the amount
of torsion in a group to estimate the size of the K-group for the group C
*-algebra and apply such an estimation to measure the degree of non-rigidi
ty of a manifold. This is joint work with Shmuel Weinberger.

SUMMARY:Noncommutative Geometry Seminar - Determinants in K-theory and oper
ator algebras
DESCRIPTION:Seminar: Noncommutative Geometry Seminar\nTitle: Determinants i
n K-theory and operator algebras\nSpeaker: Joe Migler\, Ohio State\nAbstra
ct: A determinant in algebraic K-theory is associated to any two Fredholm
operators that commute modulo the trace ideal. One can also calculate a h
omological invariant known as joint torsion. In this talk I will discuss
recent work on these invariants and some applications.

SUMMARY:Noncommutative Geometry Seminar - Nuclear C*-Algebras
DESCRIPTION:Seminar: Noncommutative Geometry Seminar\nTitle: Nuclear C*-Alg
ebras\nSpeaker: Nate Brown\, PSU\nAbstract: I'll give a status report on t
he breathtaking advances of the last year or so. Rosenberg's Conjecture is
now a theorem\, Elliott's Classification Program is essentially complete
\, the structure of "most" simple nuclear C*-algebras has been laid bare.
...there is a lot to report.

SUMMARY:Noncommutative Geometry Seminar - Automorphisms of nuclear C*-algeb
ras
DESCRIPTION:Seminar: Noncommutative Geometry Seminar\nTitle: Automorphisms
of nuclear C*-algebras\nSpeaker: Y Sato\, Kyoto University\nAbstract: In t
he recent progress of the classification\ntheorem of C*-algebras\, we have
seen connections with\nthe regularity properties and associated condition
s\nin the theory of injective von Neumann algebras\,\nwhich is shown by A.
Connes and U. Haagerup.\nIn particular\, it is known that\nthe proof with
Connes' approach is based on his\nresults on automorphisms of injective f
actors.\nIn this talk\, along the recent evolution of Elliott's program\,
\nI will revisit classification theorems of automorphisms\non nuclear C*-a
lgebras and discuss the connections between them.
