Oliver Lindblad Petersen
Postdoctoral Research Fellow, Mathematics
Current Research and Scholarly InterestsMy research concerns mathematical problems arising in General Relativity. I am especially interested in the behaviour of solutions to wave equations close to lightlike hypersurfaces, such as Cauchy horizons and event horizons. This leads to singular and degenerate hyperbolic PDEs on Lorentzian spacetimes. My research has been applied (with I. Rácz) to prove rigidity theorems for vacuum spacetimes with a compact Cauchy horizon, dropping the analyticity assumption in classical works by Moncrief and Isenberg.

Harald Trap Friis Professor
BioWhat is the origin and the global structure of the universe?
For a long time, scientists believed that our universe was born in the big bang, as an expanding ball of fire. This scenario dramatically changed during the last 35 years. Now we think that initially the universe was rapidly inflating, being in an unstable energetic vacuum-like state. It became hot only later, when this vacuum-like state decayed. Quantum fluctuations produced during inflation are responsible for galaxy formation. In some places, these quantum fluctuations are so large that they can produce new rapidly expanding parts of the universe. This process makes the universe immortal and transforms it into a multiverse, a huge fractal consisting of many exponentially large parts with different laws of low-energy physics operating in each of them.
Professor Linde is one of the authors of inflationary theory and of the theory of an eternal inflationary multiverse. His work emphasizes the cosmological implications of string theory and supergravity.
Current areas of focus:
- Construction of realistic models of inflation based on supergravity and string theory
- Investigation of conceptual issues related to the theory of inflationary multiverse -
