Spin Cohomology
George Papadopoulos
We explore differential and algebraic operations on the exterior product of spinor representations and their twists that give rise to cohomology, the spin cohomology. A linear diff…
The spinorial geometry of supersymmetric backgrounds
Joe Gillard, Ulf Gran, George Papadopoulos
We propose a new method to solve the Killing spinor equations of eleven-dimensional supergravity based on a description of spinors in terms of forms and on the Spin(1,10) gauge sym…
Power-law singularities in string theory and M-theory
G. Papadopoulos
We extend the definition of the Szekeres-Iyer power-law singularities to supergravity, string and M-theory backgrounds, and find that are characterized by Kasner type exponents. Th…
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…
