Christiane Tammer facts for kids
Christiane Tammer is a German mathematician. She is well-known for her work in a field called mathematical optimization. This area of math helps find the best possible solutions to problems.
Professor Tammer teaches at the Institute of Mathematics at the Martin Luther University of Halle-Wittenberg. She also helps lead an important math magazine called Optimization: A Journal of Mathematical Programming and Operations Research.
Some special math tools are named after her. They are called Gerstewitz functions. These tools are used in advanced math, especially in an area called vector optimization.
Education and Early Career
Christiane Tammer studied hard to become a mathematician. In 1984, she earned her doctorate degree. This is a very high university degree, like getting a PhD. She received it from the Technical University Leuna-Merseburg.
Her main project for this degree was called Beiträge zur Dualitätstheorie der nichtlinearen Vektoroptimierung. It was about complex math problems. Later, in 1991, she earned a special qualification called a habilitation at Halle. This allowed her to teach as a full professor at a university.
Books and Publications
Christiane Tammer has written several important books about mathematics. These books help other mathematicians learn about her work.
- Variational Methods in Partially Ordered Spaces (written with Alfred Göpfert, Hassan Riahi, and Constantin Zălinescu, published in 2003)
- Set-valued Optimization: An Introduction with Applications (written with Akhtar A. Khan and Constantin Zălinescu, published in 2014)
- Scalarization and Separation by Translation Invariant Functions (written with Petra Weidner, published in 2020)
She also helped edit another book. This book was a special collection of writings to celebrate Professor Wilfried Grecksch's 60th birthday. It was called Festschrift in celebration of Prof. Dr. Wilfried Grecksch's 60th birthday and was published in 2008.
