Type IIB Conifold Transitions in Cosmology
Andre Lukas, Eran Palti, P. M. Saffin
We study four-dimensional low energy effective actions for conifold transitions of Calabi-Yau spaces in the context of IIB supergravity. The actions are constucted by examining the…
Type IIA Killing spinors and calibrations
P. M. Saffin
We consider the dimensional reduction of eleven dimensional supergravity to type IIA in ten dimensions, and study the conditions for supersymmetry in terms of p-form spinor bi-line…
Dynamics of Q-Balls in an expanding universe
Eran Palti, P. M. Saffin, E. J. Copeland
We analyse the evolution of light Q-balls in a cosmological background, and find a number of interesting features. For Q-balls formed with a size comparable to the Hubble radius, w…
M-theory compactification, fluxes and AdS_4
Andre Lukas, P. M. Saffin
We analyze supersymmetric solutions of M-theory based an a seven-dimensional internal space with SU(3) structure and a four-dimensional maximally symmetric space. The most general…
