Place: Sabancı University, FENS G035
Gravity in (2+1)-dimensions has long received attention as a theoretical tool that highlights the topological aspects of gravitation. There is a recent renewal of interest with papers on the New Massive Gravity (2009) and Minimal Massive (3D) Gravity (2014). I will briefly review these models and give a generic extension that involves quadratic curvature invariants in the action, using the language of exterior differential forms. (2+1)-dimensional space-times with constant curvature and constant torsion will be given as background solutions.
T.D. received his B.S. and Ph.D. degrees in physics from METU. He taught at METU and Ankara University for many years and at Koç University since 2001. He held long-term research appointments at Yale and Brandeis Universities (USA), Lancaster University (UK), University of Vienna (Austria) and Karlsruhe University (Germany). He was an Associate Member of ICTP (Italy). Among the honours and prizes he has received, T.D. won the TUBITAK Science Prize in 1996. He published many articles in prestigious journals and is still writing papers on a very wide range of subjects in mathematical physics; covering topics in quantum field theories, gauge theories, spin structures, differential geometry and topology in physics, gravitation and cosmology.
