In this paper we construct generalised Penrose limits for the solutions of massive type IIA supergravity. We consider the Freund-Rubin type solution and apply these massive Penrose limits and obtain supersymmetric pp-wave which is standard type IIA background. The results in this paper can be easily generalised for the cases of gauged supergravities.

We present a supersymmetric action functional for the coupled system of an open fundamental superstring and super–D0–branes attached to (identified with) the string endpoints. As a preliminary step the geometrical actions for a free superD0-brane and a free type IIA superstring have been built. The pure bosonic limits of the action for the coupled system and of the equations of motion are discu...

We present an algorithm for learning a model of the effects of actions in noisy stochastic worlds. We consider learning in a 3D simulated blocks world with realistic physics. To model this world, we develop a planning representation with explicit mechanisms for expressing object reference and noise. We then present a learning algorithm that can create rules while also learning derived predicate...

In this paper we study T 2 compactification of six-dimensional massive type IIA supergravity in presence of Ramond-Ramond background fluxes. The resulting theory in four dimensions is shown to possess SL(2, R)×SL(2, R)×O(4, 20) duality symmetry. It is shown that specific elements of this symmetry relate massive type IIA compactified on K3 × T 2 (fluxes along K3) to the ordinary type IIA compact...
