The journal club is back and this Friday 5th of February we will start with a paper from 2015 on Tempo and Mode in phylogenetic comparative methods (Kaliontzopoulou and Adams). Same time and place!

Andrea Hofmann (HBV) gives the Seminar in Algebra and Algebraic Geometry:

Minimal resolutions for projective models of K3 surfaces in rational normal scrolls

Literature used in the seminar are selected chapters in the book «K3 Projective Models in Scrolls» by Trygve Johnsen and Andreas Leopold Knutsen.

Upcoming seminar in meteorology and oceanography:

Speaker: Terje K. Berntsen (Department of Geosciences)

Title: Low-threshold introduction to ski waxing - with some snow physics

Ivica Picek, university of Zagreb

Besides being a first indication for the second scalar particle, a recent hint for the 750 GeV resonance at the LHC  requires additional particles such as those employed in models of radiative neutrino mass generation. The scalar triplet realizations seem to be preferable with respect to the 2HDM benchmark and provide in the inert variant the dark matter candidates.

Abstract: As has been observed by many authors, the Drinfeld double of the q-deformation of a compact Lie group can be regarded as a quantization of the complexification of the original Lie group. Using this point of view, I will discuss irreducible unitary representations of these Drinfeld doubles.

Kostiantyn Ralchenko (Taras Shevchenko National University of Kyiv) gives a talk with the title: A generalisation of the fractional Brownian field based on non-Euclidean norms

Yuliya Mishura (Taras Shevchenko National University of Kyiv) gives a lecture with the title: What can happen between two self-similarities?

Geir Ellingsrud (UiO), gives the Seminar in Algebra and Algebraic Geometry:

Projective models of K3-surfaces II

Title: Paleoclimate: ESM used in understanding geological questions

The seminar takes place in the seminar room on the 9th floor of the computer science building.

Abstract: We discuss a way of constructing noncommutative projective manifolds as inductive and projective limits, generalizing the so-called Berezin quantization for ordinary compact Kähler manifolds. We first review the physical motivation for Berezin quantization and then discuss how the restriction to commutative manifolds limits the use of this quantization. We will also outline how our more general construction appears naturally in the study of the long-time limit of open quantum systems.

The thermal relic abundance of the dark matter is now determined observationally to a per cent level accuracy. It is also an increasingly useful tool to exclude, constrain or motivate models beyond the Standard Model of particle physics. It comes then with no surprise that in the recent years a considerable effort has been made to revise and improve some of the aspects of thermal relic density calculations. In this talk I will concentrate on the important physics concepts used in such calculations, highlighting some less commonly discussed details. Towards the end I will show some recent results, serving as examples of the relevance of the effects studied.
