Unitarity, D-brane dynamics and D-brane categories
This is a short nontechnical note summarizing the motivation and results of my recent work on D-brane categories. I also give a brief outline of how this framework can be applied to study the dynamics of topological D-branes and why this has a bearing on the homological mirror symmetry conjecture. This note can be read without any knowledge of category theory. ∗ [email protected]
متن کاملD-Brane Amplitudes in Topological String on Conifold
We study the relation between two kinds of topological amplitudes of non-compact Dbranes on conifold. In the A-model, D-branes are represented by fermion operators in the melting crystal picture and the amplitudes are given by the quantum dilogarithm. In the mirror B-model, D-branes correspond to the determinant operator det(x−M) in the ChernSimons matrix model and the amplitudes are given by t...
متن کاملTopological string theory from D-brane bound states
We investigate several examples of BPS bound states of branes and their associated topological field theories, providing a window on the nonperturbative behavior of the topological string. First, we demonstrate the existence of a large N phase transition with respect to the ’t Hooft coupling in q-deformed Yang-Mills theory on S. The Ooguri-StromingerVafa [62] relation of this theory to topologi...
متن کاملGraded Lagrangians, exotic topological D-branes and enhanced triangulated categories
I point out that (BPS saturated) A-type D-branes in superstring compactification on Calabi-Yau threefolds correspond to graded special Lagrangian submanifolds, a particular case of the graded Lagrangian submanifolds considered by M. Kontsevich and P. Seidel. Combining this with the categorical formulation of cubic string field theory in the presence of D-branes, I consider a collection of topol...
متن کاملD-Brane Dynamics in Dp-Brane Background
By using Dirac-Born-Infeld action we study the real time dynamics of D-branes in the vicinity of a stack of Dp-branes where the role of the tachyon of the open string models is played by the radial mode on the D-branes. We examine the behaviour of the tachyon potential and study the hamiltonian formulation and classical solutions of such systems. We also study the homogeneous solutions of the c...
