Alexander Schmeding
Om
Matematiker interessert i uendelig dimensjonal differensialgeometri, Lie teori og deres anvendelse. Utover forskning i ren og anvendt matematikk er jeg også interessert i matematikkdidaktikk (spesielt knyttet til høyere utdanning og lærerutdanninger).
Jeg er ansvarlig for koordinering av EVU aktivitetene ved IMF.
Bakgrunn
Jeg oppnådde min Doktorgrad (den tyske ekvivalenten til PhD) i uendelig dimensjonal Lie teori ved Universitetet i Paderborn, Tyskland i 2013. Før fullførte jeg både et diplom i matematikk (i dag tilsvarer det en mastergrad i matematikk) og et lærerutdanningsprogram (matematikk og historie) ved universitetet i Paderborn. Etter det var jeg postdoktor ved NTNU, TU Berlin og middlertidig førsteamanuensis ved Universitetet i Bergen. Før jeg begynte på NTNU var jeg førsteamanuensis ved Nord universitet i Levanger hvor jeg jobbet flere år i lærerutdanningen.
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
Lie groups and manifolds of non-smooth mappings
