On November 21-23 the Integreat team and partners convened for the first-ever kick-off meeting at the historic Tøyen Hovedgård in Oslo. The event marked a crucial milestone for the Integreat community and served as an opportunity to articulate common goals, define the purpose of upcoming projects, and facilitate team building.

This paper considers hypothesis testing in semiparametric models which may be non – regular for certain values of a (potentially infinite dimensional) nuisance parameter. In such models no (locally) regular estimator of the parameter of interest exists. The situation for testing is somewhat different: I establish that C(α) – style test statistics achieve their limiting distributions in a (locally) regular manner under mild conditions, leading to tests with correct size in situations where standard tests fail to control size. Additionally, I characterise the appropriate limit experiment in which to study local (asymptotic) optimality of tests in the case where the efficient information matrix is singular. This permits the generalisation of classical power bounds to the non – regular case. I provide appropriate statements of these bounds and give conditions under which they are attained by the proposed C(α) – style tests. Three examples are worked out in detail.

We combine a pressure correction scheme with interior penalty discontinuous Galerkin (dG) discretisation to solve the time-dependent Navier–Stokes equations. We prove unconditional energy stability and a priori error estimates for the velocity. With duality arguments, optimal L2 error rates are obtained. Convergence of the discrete pressure is also established.  Further, we propose a splitting scheme,  integrating the pressure correction approach, for the Cahn–Hilliard–Navier–Stokes system  The numerical analysis of dG combined with this scheme is discussed. Namely, we show well--posedness, stability, and error estimates. Numerical results with manufactured solutions display our theoretical findings, and a spinodal decomposition example portrays the robustness of our approach.

For 200 år siden oppdaget geologen Jens Esmark, gjennom å observere formasjoner i landskapet, at Jorden en gang måtte ha vært dekket av is. Ved å studere isbreer kan dagens forskere rekonstruere historiske klimaforhold og miljøendringer, kartlegge hvordan landskapet har forandret seg gjennom tiden, samt sette dagens hurtige klimaendringer i et lenger perspektiv.

Traditional quantile estimators are not well-suited for data streams because the memory and computational time increase with the volume of data received from the stream. Incremental quantile estimators refer to a class of methods designed to maintain quantile estimates for data streams. These methods operate by making small updates to the estimate every time a new observation is received from the stream. In this presentation, I will introduce some of the incremental quantile estimators we have developed.

Elise Lockwood: 

Computational thinking and activity are becoming an increasingly important aspect of what it means to conduct scientific and mathematical work. In light of this, there is a need for mathematics education studies that examine the ways in which students engage with computational tools as they reason about scientific and mathematical concepts.

In this talk, I provide an example of how such computational activity can support the desirable mathematical practice of generalizing. I provide data from an interview with a student who engaged in generalizing activity while using Python to solve combinatorial problems.

I connect his work to the literature on generalization and suggest that there are promising avenues to pursue in leveraging computing for such mathematical practices. I conclude by framing this work within ongoing efforts to better understand the nature of computational thinking and activity for undergraduate students.
