Multiparameter Brane Solutions by Boosts, S and T dualities
S. Kalyana Rama
We show that the multiparameter (intersecting) brane solutions of string/M theories given in the literature can all be obtained by a suitable combination of boosts in eleven dimens…
Classical Velocity in kappa-deformed Poincare Algebra and a Maximum Acceleration
S. Kalyana Rama
We study the commutators of the kappa-deformed Poincare Algebra (kappaPA) in an arbitrary basis. It is known that the two recently studied doubly special relativity theories corres…
Brane World Scenario with m-form field: Stabilisation of Radion Modulus and Self Tuning Solutions
S. Kalyana Rama
We consider (n + m + 1) dimensional bulk spacetime, containing flat (n + m - 1) dimensional parallel branes, with topology R^{n - 1} \times T^m. We assume that the graviton and an…
A Note on Holographic Principle in models of Extended Inflation type
S. Kalyana rama
We present a simple derivation of an upper bound on the average size of the true vacuum bubbles at the end of inflation, in models of extended inflation type. The derivation uses t…
Graviton-Dilaton Cosmology
S. Kalyana Rama
We show that the evolution of the universe is singularity free in a class of graviton-dilaton models.
Implications of Some Static Spherically Symmetric Graviton-Dilaton Solutions in Brans-Dicke and Low Energy String Theory
S. Kalyana Rama
Analysing the static, spherically symmetric graviton-dilaton solutions in low energy string and Brans-Dicke theory, we find the following. For a charge neutral point star, these th…
