Abstract: I will start with a biographical sketch of Yves Meyer, and continue with a review of the strengths and weaknesses of the Fourier transform, followed by a discussion of the alternatives proposed by Dennis Gabor (logons) and Jean Morlet (wavelets).

Topological cyclic homology is a variant of negative cyclic homology which was introduced by Bökstedt, Hsiang and Madsen. They invented topological cyclic homology to study algebraic K-theory but in recent years it has become more and more important as an invariant in its own right. We present a new formula for topological cyclic homology and give an entirely model independent construction. If time permits we explain consequences and further directions.

Joint work with Bjørn I. Dundas. We prove that algebraic K-theory, topological Hochschild homology and topological cyclic homology satisfy cubical and cosimplicial descent at connective structured ring spectra along 1-connected maps of such ring spectra.

Activity at IFE Wind Energy: numerical modeling of offshore wind turbines

IFE (Institutt for Energiteknikk) is a research center located in Kjeller. The wind group at IFE mainly works with the development and analysis of new cost effective concepts for offshore wind energy, both concerning innovative rotor designs and new concepts for substructures. The group main investigation tool is the in-house software 3DFloat, an aero-elastic code which can simulate the whole wind turbine structure when exposed to the associated environmental loads (wind loads, hydrodynamic loads, soil loads if bottom-fixed).

In the presentation, an insight into the wave kinematics and wave loads modeling tools that are currently included in 3DFloat will be provided.

The second Scandinavian Gathering Around Remarkable Discrete Mathematics

Tid og sted: 26. apr. 2017 14:15 - 16:00, B 738

 In this talk all spaces and spectra will be localised at 2. Many E-infinity ring spectra turn out to be `finitely generated' in the sense that there is finite CW spectrum and a map from the free E-infinity ring spectrum generated by it inducing an epimorphism in mod 2 homology. This turns out to be an interesting condition and I will discuss some examples such as HZ, kO, kU, tmf and tmf_1(3). One long term goal of this work is to produce `ultra-generalised Brown-Gitler spectra' and I will discuss this idea if there is time.

Given a knot K in the 3-sphere, we use Heegaard Floer correction terms to give lower bounds on the first Betti number of (orientable and non-orientable) surfaces in the 4-ball with boundary K. An amusing feature of the non-orientable bound is its superadditivity with respect to connected sums. This is joint work with Marco Marengon. If time permits, I will discuss relations with deformations of singularities of curves (joint work with József Bodnár and Daniele Celoria).
