NuHAG goalsBridge the gap between theory and
numerical applicationGo for efficient algorithms which are
applicable to real life problemsProvide theoretical backup which
allows to guarantee convergence ratesRefresh theoretical concepts by
models relevant for scientific/techn. applications

Prof. Hans Georg Feichtinger 12
NuHAG and EducationEducation to application oriented
research by combining mathematical modelling with numerical realization
Making students familiar with the situation of project formulation, interaction with scientists at large, „bi-linguality“ relevant!
Presentation and formulation of resultsDiscuss goals and basic ideas in non-
mathematical terms, present relevance
