CIME & CEES Extra seminar by Timothy D. Read from Emory University School of Medicine

Abstract: We talk about independent resolutions for dynamical systems on totally disconnected spaces. Building on earlier work by Cuntz, Echterhoff and Li that allows one to compute the K-theory of totally disconnected systems that admit a so called independent invariant regular basis, we show how any totally disconnected dynamical system admits a resolution of such systems, which in some cases allows for K-theory computations. Based on work by me and X. Li.

CEES Extra seminar/Faculty of Dentistry seminar by Bill Hanage from Harvard School of Public Health

Marco Matassa (UiO) will give a talk with title: On dimension and integration for spectral triples associated to quantum groups

Abstract: Abstract: I will discuss some aspects of the notions of spectral dimension and non-commutative integral in the context of modular spectral triples. I will focus on two examples: the modular spectral triple for SU_q(2) introduced by Kaad and Senior and the family of spectral triples for quantum projective spaces introduced by D'Andrea and D?browski.

This years Skolem Lecturer lecturer is professor Kit Fine, from New York University. Fine is known for his work in logic, the philosophy of language and metaphysics.

Jens Kaad (Trieste), will give a talk with title "Joint torsion line bundles of commuting operators"

Abstract:

In this talk I¡¯ll associate a holomorphic line bundle to any commuting tuple of bounded operators on a Hilbert space. The transition functions for this bundle are given by the joint torsion which compares determinants of Fredholm complexes. The joint torsion is an invariant of the second algebraic K-group of the Calkin algebra (bounded operators modulo trace class operators). The main step is to prove that the transition functions for the joint torsion line bundle are indeed holomorphic. This is carried out by studying the Quillen-Freed holomorphic determinant line bundle over the space of Fredholm complexes. In particular I will construct a holomorphic section of a certain pull-back of this bundle. The talk is based on joint work with Ryszard Nest.

Flow induced vibration (FIV) is a recent discipline in Flow Assurance which focuses on the piping and equipment vibrations caused by the internal flow of gas, oil and/or water in subsea production systems (SPS). Those vibrations may cause fatigue failure at weak spots in the piping such as welds and tees. Due to recent incidents and ever-increasing production rates and velocities, FIV is now considered as a major limiting factor in the design and operation of SPS. Based on real cases and ongoing projects, this presentation provides an introduction to the following aspects: fluid-structure interaction mechanism, fatigue mechanism, design requirements for SPS, analysis tools and vibration monitoring techniques.

Roberto Conti (Sapienza Universit¨¤ di Roma) will give a talk with title:  Asymptotic morphisms in local quantum physics and study of some models

Abstract:

 We discuss a notion of asymptotic morphisms that is suitable for a description of superselection sectors of a scaling limit theory. In some models, this leads to interesting questions about the explicit form of certain modular operators. (This talk is based on joint work with D. Guido and G. Morsella).
