Volterra Lecture by Professor Leif Andersson ,Uppsala University, Texas A&M University, Swedish University of Agricultural Sciences

By Filip Volckaert from the University of Leuven

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).

Nacira Agram (University of Oslo) gives a lecture with the title: A Hida-Malliavin white noise calculus approach to optimal control

Roxana Dumitrescu (King’s College, London) gives a lecture with the title: Game options in an imperfect market with default

We will have a “mingle” meeting. There will be updates from Kristine and Per on the running of the institute. But fear not, there will also be plenty of time for informal chat and eating of cake. All are welcome to the lobby on the first floor.

Hvordan jobber Tim Wendelboe i sin jakt på den perfekte kopp med kaffe?

Tim er både kaffebonde, kaffebrenner og barista og vil gi deg et lite innblikk i alt arbeidet som ligger bak hver kopp kaffe som serveres i hans kaffebar på Grünerløkka.

In the 80's Bökstedt introduced THH(A), the Topological Hochschild homology of a ring A, and a trace map from algebraic K-theory of A to THH(A). This trace map, along with the circle action on THH, have since been used extensively to make calculations of algebraic K-theory. When the ring A has an anti-involution Hesselholt and Madsen have promoted the spectrum K(A) to a genuine Z/2-spectrum whose fixed points is the K-theory of Hermitian forms over A. They also introduced Real topological Hochschild homology THR(A), which is a genuine equivariant refinement of THH, and Dotto constructed an equivariant refinement of Bökstedt's trace map. I will report on recent joint work with Dotto, Patchkoria and Reeh on models for the spectrum THR(A) and calculations of its RO(Z/2)-graded homotopy groups. 

Adam Sørensen (Oslo) will give a talk with title: Overlapping qubits

Abstract: I will discuss the paper "Overlapping Qubits" by Chao, Reichardt, Sutherland, and Vidick (arXiv:1701.01062 - category: Quantum Physics!). Qubits are the bits of quantum computing. In the paper the authors take the point of view that a qubit mathematically is described by a pair of anticommuting reflections on a finite dimensional Hilbert space. Two qubits are independent if their defining operators commute. The central point of the paper is that when performing observations we should not expect two qubits to be exactly independent, rather we should expect them to be almost independent, i.e. the norms of the commutators should be small. This naturally leads to questions about almost commuting matrices, which is why I care. I will attempt to explain how questions of almost commuting matrices come up, and how the physicists answer them.
