This paper deals with black holes, bubbles and orbifolds in GaussBonnet theory in five dimensional anti de Sitter space. In particular, we study stable, unstable and metastable phases of black holesâ€¦ (More)

This is a continuation of our earlier work where we constructed a phenomenologically motivated effective action of the boundary gauge theory at finite temperature and finite gauge coupling on S Ã—S1.â€¦ (More)

Observer design method for Lipschitz nonlinear systems, reported in the literature, did not consider the distribution matrix of nonlinearity and state dependence of nonlinear functions in the stateâ€¦ (More)

We find solutions of 11-dimensional supergravity for M5-branes wrapped on Riemann surfaces. These solutions preserve N = 2 fourdimensional supersymmetry. They are dual to N = 2 gauge theories,â€¦ (More)

We calculate the potential between bound states of D-branes of different dimension in IIB matrix model upto one loop order and find nice agreement with the open string calculations in short and largeâ€¦ (More)

We present a class of static membrane solutions, with non-flat worldvolume geometry, in the eleven dimensional supergravity with source terms. This class of solutions contains supersymmetric as wellâ€¦ (More)

We study D1-branes on the fourfold C/(Z2 Ã— Z2 Ã— Z2), in the presence of discrete torsion. Discrete torsion is incorporated in the gauge theory of the D 1-branes by considering a projectiveâ€¦ (More)

We study Seiberg duality of quiver gauge theories associate d to the complex cone over the second del Pezzo surface. Homomorphisms in the path algebra of the quivers in each of these cases satisfyâ€¦ (More)

Fractional branes on the non-compact orbifold C3/Z5 are studied. First, the boundary state description of the fractional branes are obtained. The open-string Witten ndex calculated using these statesâ€¦ (More)

We study constant dilaton supersymmetric solutions of type IIB Supergravity with 5form and 3-form flux with isometry group U(1) Ã—Z3. Some of these solutions correspond to marginal perturbations ofâ€¦ (More)
