Some Issues in Noncommutative Solitons as D-branes
S. P. de Alwis, A. T. Flournoy
We investigate and interpret a large class of soliton solutions found in noncommutative tachyon condensation. These constructions make extensive use of the idea that Dp-branes may…
The Cosmological Constant in Calabi-Yau 3-fold Compactifications of the Horava-Witten Theory
S. P. de Alwis, Nikolaos Irges
Brane world scenarios offer a way of setting the cosmological constant to zero after supersymmetry breaking provided there is a sufficient number of adjustable integration constant…
Brane Worlds, the Cosmological Constant and String Theory
S. P. de Alwis, A. T. Flournoy, N. Irges
We argue that traditional methods of compactification of string theory make it very difficult to understand how the cosmological constant becomes zero. String inspired models can g…
String Universality
R. Brustein, S. P. de Alwis
If there is a single underlying "theory of everything" which in some limits of its "moduli space" reduces to the five weakly coupled string theories in 10D, and 11D SUGRA, then it…
Brane World Scenarios and the Cosmological Constant
S. P. de Alwis
Brane world scenarios offer a way of ensuring that a Poincare invariant four dimensional world can emerge, without fine tuning, as a solution to the equations of motion of an effec…
