2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/52991I review some aspects of obtaining inflation from string theory, in particular brane-antibrane inflation within the framework of KKLMMT, and racetrack inflation. Further, I discuss recent work on the problem of reheating after brane-antibrane annihilation, and possible distinctive features of production of cosmic string and brane defects at this time.13 pages, 14 figures; invited talk at JGRG14 conference, Kyoto, Japan, 2 Dec. 2004High Energy Physics - Theorytext
