Matrix Model in a Class of Time Dependent Supersymmetric Backgrounds
We discuss the matrix model in a class of 11D time dependent supersymmetric backgrounds as obtained in [7]. We construct the matrix model action through the matrix regularization of the membrane action in the background. We show that the action is exact to all order of fermionic coordinates. Furthermore We discuss the fuzzy sphere solutions in this background. Email:[email protected] Email:bch...
متن کاملSupersymmetric Intersecting Branes in Time-dependent Backgrounds
We construct a family of supersymmetric solutions in time-dependent backgrounds in supergravity theories. One class of the solutions are intersecting brane solutions and another class are brane solutions in pp-wave backgrounds, and their intersection rules are also given. The relation to existing literature is also discussed. An example of D1-D5 with linear null dilaton together with its possib...
متن کاملSupersymmetric heterotic string backgrounds
We present the main features of the solution of the gravitino and dilatino Killing spinor equations derived in hep-th/0510176 and hep-th/0703143 which have led to the classification of geometric types of all type I backgrounds. We then apply these results to the supersymmetric backgrounds of the heterotic string. In particular, we solve the gaugino Killing spinor equation together with the othe...
متن کاملStrings in Singular Time - Dependent Backgrounds 1
We review the construction of time-dependent backgrounds with space-like singularities. We mainly consider exact CFT backgrounds. The algebraic and geometric aspects of these backgrounds are discussed. Physical issues, results and difficulties associated with such systems are reviewed. Finally, we present some new results: a two dimensional cosmology in the presence of an Abelian gauge field de...
متن کاملSupersymmetric backgrounds from 5 d
We construct curved backgrounds with Euclidean signature admitting rigid supersymmetry by using a 5d N = 1 off-shell Poincaré supergravity. We solve the conditions for the background Weyl multiplet and vector multiplets that preserve at least one supersymmetry parameterized by a symplectic Majorana spinor, and represent the solution in terms of several independent fields. We also show that the ...
