Christiane Tretter (born 28 December 1964)[1] is a German mathematician and mathematical physicist who works as a professor in the Mathematical Institute (MAI) of the University of Bern in Switzerland,and as managing director of the institute.[2] Her research interests include differential operators and spectral theory.
Tretter studied mathematics,with a minor in physics,at the University of Regensburg,earning a diploma in 1989,a Ph.D. in 1992,and a habilitation in 1998.[1] Her doctoral dissertation,Asymptotische Randbedingungen für Entwicklungssätze bei Randeigenwertproblemen zu mit -abhängigen Randbedingungen,was supervised by Reinhard Mennicken.[3]
Tretter is the author of two mathematical monographs,Spectral Theory of Block Operator Matrices and Applications (2008)[4] and On Lambda-Nonlinear-Boundary-Eigenvalue-Problems (1993),[5] and of two textbooks in mathematical analysis.
