[5] Her dissertation, A Characterization of the Non-Local Boundary Value Problems Associated With an Elliptic Operator, was supervised by Ralph S.
in 1975 at the University of Copenhagen, with the habilitation thesis Semiboundedness and other properties of normal boundary problems for elliptic partial differential operators.
