Geometrical Tachyon Dynamics in the Background of a Bulk Tachyon Field
Eleftherios Papantonopoulos, Ioanna Pappa, Vassilios Zamarias
We study the dynamics of a D3-brane moving in the background of a bulk tachyon field of a D3-brane solution of Type-0 string theory. We show that the dynamics on the probe D3-brane…

The geometry of wrapped M5-branes in Calabi-Yau 2-folds
Ansar Fayyazuddin, Tasneem Zehra Husain, Ioanna Pappa
We study the geometry of M5-branes wrapping a 2-cycle which is Special Lagrangian with respect to a specific complex structure in a Calabi-Yau two-fold. Using methods recently appl…

Cosmological Evolution of a Brane Universe in a Type 0 String Background
I. Pappa
We study the cosmological evolution of a D3-brane Universe in a type 0 string background. We follow the brane universe along the radial coordinate of the background and we calculat…
