Two and three loop alpha' corrections to T-duality: Kasner and Schwarzschild
Ghasem Exirifard, Martin O'Loughlin
Two and three loop alpha' corrections are calculated for Kasner and Schwarzschild metrics, and their T-duals, in the bosonic string theory. These metrics are used to obtain the two…

The Universality of Penrose Limits near Space-Time Singularities
Matthias Blau, Monica Borunda, Martin O'Loughlin +1
We prove that Penrose limits of metrics with arbitrary singularities of power-law type show a universal leading u^{-2}-behaviour near the singularity provided that the dominant ene…
