Laufzeit: 01.01.2002 - 31.12.2010

Die Eigenfrequenzen der mechanischen Schwingungen eines Fluids, in den

feste Strukturen gesenkt sind, wird durch rationale variationelle

Eigenwertaufgaben beschrieben, die häufig nichtlokale Randbedingungen besitzen.

Ziel dieses Projektes ist es, für lineare Eigenwertaufgaben bekannte Ergebnisse

wie variationelle Charakterisierungen, Vergleichssätze oder Approximationseigenschaften

zu übertragen und hiermit zu effizienten Algorithmen zu gelangen.
