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.

This is the first of two lectures by Anders Hansen (Cambridge Univ. and UiO) on Compressed sensing - Structure and Imaging.

Willi Sauerbrei (Institute for Medical Biometry and Statistics, University of Freiburg) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.

This is the second of two lectures by Anders Hansen (Cambridge Univ. and UiO) on Compressed sensing - Structure and Imaging.

This is the first of two lectures by Anders Hansen (Cambridge Univ. and UiO) on Foundational Computational Problems in l^1 and Total Variation Regularisation.

*Abstract: I will discuss the two main syntheses that occured duing the "wavelet revolution" in the second half of the 1980s: one concerning the many aspects of what we now call wavelets, another concerning the relations between conjugate mirror filters, multiresolution approximations and orthonormal wavelet bases.*

Coffee/tea and cookies will be served from 14.00 to 14.30.

A double seminar will be held in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.

On 4-6 July 2017, the second conference on the mathematics of energy markets will take place at the Wolfgang Pauli Institute (WPI) in Vienna, Austria. The conference is an activity within the thematic program "Mathematics for Risk in Finance and Energy" at the WPI.

We welcome participants from academia and industry to take part in this event.

A **pre-conference intensive course** will be organized on Monday July 3. The course leader will be Professor Almut Veraart, who will give a course on Ambit stochastics with applications to commodity markets. See here for more details on the intensive course.

**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.

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).
