This Friday the 3rd of June we will discuss a recent paper by Arif et al (2013): "Genetic and developmental analysis of differences in eye and face morphology between Drosophila simulans and Drosophila mauritiana".

Hope to see you there!

Trait-based demographic models such as IPMs relate not only future adult size but also offspring size to the current size of an individual. This is in stark contrast to the quantitative genetic approach, and may have consequences for the predictions of evolutionary dynamics.

We look into this issue with a recent paper from Chevin:

Fredrik Lanner, assistant professor, Karolinska Institutet, will present the work leading up to the recent publication on gene expression in early human embryos, and present his plans to use CRISPR technology to edit genes in early human embryos, as one of the first researchers in the world.

We invite you to a one-day workshop celebrating Professor Bent Natvig's 70th anniversary. Invited speakers will present recent developments in some of the areas where Bent has made significant contributions, including reliability theory and mathematical statistics.

Bent Natvig has, since 1986, been a professor of mathematical statistics at the Department of Mathematics. He is the author of a long list of important papers published in top-ranked scientific journals as well as the recent book entitled "Multistate Systems Reliability Theory with Applications" (John Wiley & Sons). At our department, Bent has taken the leading role in the area of reliability theory. On August 1 this year, he turns 70.

Welcome to the GeoHyd Lunch Seminar on Thursday May 26th @ 12:15 in aud. 1 in the Geology building.

Abhik Ghosh (Dept. of Biostatistics, UiO) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15. 

Welcome to the GeoHyd Lunch Seminar on Tuesday May 24th @ 12:15 in aud. 2 in the Geology building.

Welcome to the GeoHyd Lunch Seminar on Friday May 20th @ 12:15 in aud. 1 in the Geology building.

We will have a new “mingle” meeting on Friday at 11.15 (as usual). The main attraction will be Ingunn Wehus and Signe Riemer-Sorensen.   

 Otherwise there will be updates from Kristine and Viggo 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.

Alessandro Oneto​ (Stockholm)​ gives the Seminar in Algebra and Algebraic Geometry:

Ideals of points and Waring problems for polynomials​

Abstract: This talk addresses some of the fundamental barriers in the theory of computations. Many computational problems can be solved as follows: a sequence of approximations is created by an algorithm, and the solution to the problem is the limit of this sequence (think about computing eigenvalues of a matrix for example). However, as we demonstrate, for several basic problems in computations such as computing spectra of operators, solutions to inverse problems, roots of polynomials using rational maps, solutions to convex optimization problems, imaging problems etc. such a procedure based on one limit is impossible. Yet, one can compute solutions to these problems, but only by using several limits. This may come as a surprise, however, this touches onto the boundaries of computational mathematics. To analyze this phenomenon we use the Solvability Complexity Index (SCI). The SCI is the smallest number of limits needed in order to compute a desired quantity. The SCI phenomenon is independent of the axiomatic setup and hence any theory aiming at establishing the foundations of computational mathematics will have to include the so called SCI Hierarchy. We will specifically discuss the vast amount of classification problems in this non-collapsing complexity/computability hierarchy that occur in inverse problems, compressed sensing problems, l1 and TV optimization problems, spectral problems, PDEs and computational mathematics in general.
