Juergen Sprekels
Karl Weierstrass and optimization

Chair: Richard Warren Cottle

The work of Karl Weierstrass, the outstanding Berlin mathematician who was one of leading mathematical researchers of the second half of the nineteenth century, had a deep impact on the theory of optimization and on variational calculus. In this talk, we review some aspects of his contributions to the field.


Biographical sketch:
J├╝rgen Sprekels, born 1948 in Hamburg, Germany, studied mathematics at the University of Hamburg, where he received his PhD in 1975 and his habilitation in 1977. After professorships in Augsburg (1981-88) and Essen (1988-94), he became Full Professor for Applied Analysis at the Humboldt-Universit├Ąt zu Berlin in 1994. Since 1994 he has been the director of the Weierstrass Institute for Applied Analysis and Stochastics (WIAS) in Berlin, the non-university mathematical research institute that hosts the Secretariat of the International Mathematical Union (IMU) and the German Mathematical Society (DMV). He was also one of the founders of the mathematical research center MATHEON in Berlin. His research focuses on the analysis and optimal control of nonlinear systems of PDEs arising in applications, with an emphasis on hysteresis phenomena, phase transitions, and free boundary problems. He conducted several industrial cooperation projects, in particular, in the growth of semiconductor bulk single crystals. He (co-)authored two research monographs and more than 150 papers in refereed journals and conference proceedings.
