Sondre Tesdal Galtung
Om
Mine forskingsinteresser er i hovudsak knytta til partielle differensiallikningar og numeriske metodar. Dei famnar mellom anna om, men er ikkje avgrensa til:
- Likningar med opphav i fluiddynamikk.
- Hyperbolske konserveringslover.
- Bruk av variasjonsrekning og optimal kontroll innan matematisk modellering.
Eg er for tida vitskapleg gjest på University of Oxford fram til sommaren 2023.
