Alexander Schmeding

Om

Jeg er matematiker og forsker på uendeligdimensjonal differensialgeometri, Lie teori og anvendelser av disse fagområdene. Jeg arbeider med både ren og anvendt matematikk og er dessuten interessert i matematikkdidaktikk, særlig innen høyere utdanning og lærerutdanning.

Jeg er studieprogramleder for MLREAL.

Bakgrunn

Jeg tok doktorgraden min i uendeligdimensjonal Lie-teori ved Universitetet i Paderborn i Tyskland i 2013. Ved samme universitet fullførte jeg tidligere et diplomstudium i matematikk, tilsvarende en mastergrad, samt en lærerutdanning i matematikk og historie.

Etter doktorgraden arbeidet jeg som postdoktor ved NTNU og TU Berlin og som midlertidig førsteamanuensis ved Universitetet i Bergen. Før jeg begynte ved NTNU, var jeg førsteamanuensis ved Nord universitet i Levanger, hvor jeg arbeidet i lærerutdanningen i flere år.

Forskning

My research centers around infinite-dimensional differential geometry, Lie theory and their applications. Infinite-dimensional Lie groups arise naturally for example in the theory of hydrodynamics. The flow of a fluid particle (under periodic boundary conditions) can be modelled as a curve taking values in the group of volume preserving diffeomorphism on the torus. The resulting curve turns out to be connected to Riemannian geometry on the infinite-dimensional Lie group of volume preserving diffeomorphisms. Hence infinite-dimensional geometric tools and insights can be used to study flows in hydrodynamics. This example shows one of the subtle connections between finite and infinite-dimensional geometry I am interested in.

Beyond research in geometry, I am also interested in questions connected to the didactics of mathematics related to higher education at the university level and teacher education.

Research interests (mathematics)

Lie groups of diffeomorphisms
Lie groupoids and their representations
manifolds of mappings
(weak) Riemannian geometry on infinite-dimensional spaces
Interactions of differential geometry with rough path theory and Hopf algebras
Applications of the above (e.g. Geometric hydrodynamics and shape analysis)

Research interests (didactics of mathematics)

programming in mathematics textbooks for norwegian schools
peer- and self-evaluation activities in higher education

CODYSMA project

The project CODYSMA: Computational Dynamics and Stochastics on Manifolds is a five year project which started January 1st, 2020 supported by the Norwegian Research Council through the program FRIPRO.

Lie groups and manifolds of non-smooth mappings

We propose to construct and study Lie groups of paths of bounded variation with values in a Lie group. The driving motivation comes from the theory of rough paths. Rough path theory provides a fresh look at differential equations driven by rough signals.

An Introduction to Infinite-Dimensional Differential Geometry

Introducing foundational concepts in infinite-dimensional differential geometry, this book focuses on two main areas of infinite-dimensional geometry: infinite-dimensional Lie groups and weak Riemannian geometry. Available as Open Access.
