Hylleraas seminar, hosted in Oslo
By Muhammed Fatih Sert, Department of Geosciences, UiT The Arctic University of Norway
Welcome to our GeoHyd Lunch Seminar on Friday 1th of November @ 12:15 in Aud. 1 in the Geology Building. The seminar is held by Marco Mazzolini (University of Oslo).
Heat and mass transfer occurs in several natural flows, as well as in many industries. This process is multiscale by nature: the chemistry at the interfaces affects the macroscopic system behavior (e.g. heat transfer coefficients) and the large-scale flow structures determine the details of the local mass and energy fluxes; as example, multicomponent droplet evaporation displays a complex interplay between density, concentration and temperature gradients. The talk will focus on recent advancements in modelling heat and mass transfer in laminar and turbulent flows. We explore various interface capturing methods, including diffuse-interface and sharp-interface approaches, and their coupling with phase-change models to account for interfacial heat and mass exchange. Specifically, we present a formulation based on the diffuse-interface Baer-Nunziato models, where mass transfer is driven by chemical potential disequilibrium. A pressure-based formulation is employed to mitigate time step restrictions while maintaining complex thermodynamic accuracy. Simulations of evaporative flows will be showcased, comparing the performance of diffuse-interface methods with sharp-interface approaches.
Mirror symmetry predicts that the symplectic geometry of a manifold is equivalent to the complex geometry of the mirror manifold. In particular, enumerative mirror symmetry relates quantum cohomology (Gromov-Witten invariants) of a manifold with period integrals of the mirror. A fundamental question in mirror symmetry is to construct mirrors. I will explain Gross-Siebert's intrinsic mirror symmetry which gives a mirror construction using relative quantum cohomology. More precisely, one considers a maximally unipotent monodromy degeneration of a Calabi—Yau manifold and take proj of the degree zero part of a relative quantum cohomology ring associated with the degeneration. Theta functions form a canonical basis of the degree zero part of the relative quantum cohomology ring. Theta functions can be defined in terms of punctured Gromov-Witten invariants of the broken line type. I will explain a variant of intrinsic mirror symmetry using orbifold Gromov-Witten invariants of root stacks, theta functions for general snc pairs and possible applications to questions in mirror symmetry.

Join the dScience lunch seminar at the dScience lounge to hear biostatistician Harald Weedon-Fekjær discuss the complexities of mammography screening. He will explore the debate around non-progressive tumours detected through screening and how statistical modeling helps provide insights at the population level. If you’re interested in the public health balance of cancer screening, this talk is not to be missed.
