Modified C0 interior penalty analysis for fourth order Dirichlet boundary control problem and a posteriori error estimate
Sudipto Chowdhury, Divay Garg, Ravina Shokeen
We revisit the L2 norm error estimate for the C0 interior penalty analysis of fourth order Dirichlet boundary control problem. The L2 norm estimate for the optimal control is deriv…
A posteriori error analysis for a distributed optimal control problem governed by the von Kármán equations
Sudipto Chowdhury, Asha K. Dond, Neela Nataraj +1
This article discusses numerical analysis of the distributed optimal control problem governed by the von Kármán equations defined on a polygonal domain in . The state…
On Interior Penalty Method for Fourth Order Dirichlet Boundary Control Problem and a New Error Analysis for Fourth Order Elliptic Equation with Cahn-Hilliard Boundary Condition
Sudipto Chowdhury
In this paper, we revisit the -norm error estimate for -interior penalty analysis of Dirichlet boundary control problem governed by biharmonic operator. In this work, we…
Finite Temperature Corrections to Tachyon Mass in Intersecting D-Branes
Varun Sethi, Sudipto Paul Chowdhury, Swarnendu Sarkar
We continue with the analysis of finite temperature corrections to the Tachyon mass in intersecting branes which was initiated in arxiv:1403.0389. In this paper we extend the compu…
Non-vacuum AdS cosmology and comments on gauge theory correlator
Soumyabrata Chatterjee, Sudipto Paul Chowdhury, Sudipta Mukherji +1
Several time dependent backgrounds, with perfect fluid matter, can be used to construct solutions of Einstein equations in the presence of a negative cosmological constant along wi…
A Frame Work for the Error Analysis of Discontinuous Finite Element Methods for Elliptic Optimal Control Problems and Applications to IP methods
Sudipto Chowdhury, Thirupathi Gudi, A. K. Nandakumaran
In this article, an abstract framework for the error analysis of discontinuous Galerkin methods for control constrained optimal control problems is developed. The analysis establis…
BCS Instability and Finite Temperature Corrections to Tachyon Mass in Intersecting D1-Branes
Sudipto Paul Chowdhury, Swarnendu Sarkar, B. Sathiapalan
A holographic description of BCS superconductivity is given in arxiv:1104.2843. This model was constructed by insertion of a pair of D8-branes on a D4-background. The spectrum of i…
Some BPS configurations of the BLG Theory
Sudipto Paul Chowdhury, Shankhadeep Chakrabortty, Koushik Ray
We obtain BPS configurations of the BLG theory and its variant including mass terms for scalars and fermions in addition to a background field with different world-volume and R-sym…
Soft supersymmetry breaking with tiny cosmological constant in flux compactified N=1 Supergravity
Debottam Das, Joydip Mitra, Sudipto Paul Chowdhury +1
Using the flux compactification scenario in a generic supergravity model we construct a set of conditions which are necessary to generate de-Sitter or anti de-Sitter vacua for appr…
Moduli and BPS configurations of the BLG theory
Shankhadeep Chakrabortty, Sudipto Paul Chowdhury, Thomas Köppe +1
We study the moduli space of scalars in the BLG theory with and without a constant background four-form field. The classical vacuum moduli space is sixteen-dimensional in the absen…
BLG theory with generalized Jordan triple systems
Sudipto Paul Chowdhury, Subir Mukhopadhyay, Koushik Ray
We use a generalized Jordan algebra of the second kind to study the recently proposed BLG theory of multiple M2-branes. We find the restriction imposed on the ternary product from…
Superstring partition functions in the doubled formalism
Sudipto Paul Chowdhury
Computation of superstring partition function for the non-linear sigma model on the product of a two-torus and its dual within the scope of the doubled formalism is presented. We v…
