Christiane Tammer facts for kids

Christiane Tammer is a German mathematician. She is known for her important work in a field called mathematical optimization. This is about finding the best possible solutions to problems. Think of it like finding the most efficient way to do something. She teaches at the Martin Luther University of Halle-Wittenberg in Germany. She is also the main editor for a science magazine called Optimization: A Journal of Mathematical Programming and Operations Research.

Some special ideas in math are named after her. These are called the Gerstewitz functions. They are used in an area of math called vector optimization. This is a way to solve problems where you have many goals at once.

Her Education Journey

Christiane Tammer studied very hard to become a mathematician.

Getting Her Doctorate

In 1984, she earned a special degree called a doctorate (Dr. rer. nat.). This is a very high university degree. She earned it from the Technical University Leuna-Merseburg. Her main project for this degree was called Beiträge zur Dualitätstheorie der nichtlinearen Vektoroptimierung. Her professor, Alfred Göpfert, helped her with this work.

Becoming a Professor

Later, in 1991, she completed another important step in her academic career. This was called a habilitation at Halle University. This qualification showed she was ready to teach as a professor.

Books She Has Written

Christiane Tammer has written several important books about mathematics. These books help other mathematicians learn about her work.

• Variational Methods in Partially Ordered Spaces (with Alfred Göpfert, Hassan Riahi, and Constantin Zălinescu, Springer, 2003)
• Set-valued Optimization: An Introduction with Applications (with Akhtar A. Khan and Constantin Zălinescu, Springer, 2014)
• Scalarization and Separation by Translation Invariant Functions (with Petra Weidner, Springer, 2020)

She also helped to edit another book. It was called Festschrift in celebration of Prof. Dr. Wilfried Grecksch's 60th birthday (Shaker, 2008). She worked on this book with Frank Heyde.
