# D Branes in String Theory, I

@inproceedings{Vecchia1999DBI, title={D Branes in String Theory, I}, author={Paolo Di Vecchia and Antonella Liccardo}, year={1999} }

In these lectures we present a detailed description of the origin and of the construction of the boundary state that is now widely used for studying the properties of D branes.

### The Geometry of Fractional D 1-branes

- Mathematics
- 2004

We find explicit solutions of Type IIB string theory on R/Z2 corresponding to the classical geometry of fractional D1-branes. From the supergravity solution obtained, we capture perturbative…

We find explicit solutions of type IIB string theory on R-4/Z(2) corresponding to the classical geometry of fractional D1-branes. From the supergravity solution obtained, we capture perturbative…

### Topological Strings and $D$-Branes

- Mathematics
- 2004

In this talk we give a brief review of the algebraic structure behind the open and closed topological strings and $D$-branes and emphasize the role of tensor category and the Frobenius algebra. Also,…

### Lectures on non-BPS Dirichlet branes

- Mathematics, Philosophy
- 2000

A comprehensive introduction to the boundary state approach to Dirichlet branes is given. Various examples of BPS and non-BPS Dirichlet branes are discussed. In particular, the non-BPS states in the…

### Notes on D-branes

- Physics
- 1996

This is a series of remedial lectures on open and unoriented strings for the heterotic string generation. The particular focus is on the interesting features that arise under T-duality---D-branes and…

### Type I D-particle and its interactions

- Mathematics

In this paper, we generalize a boundary state to the one incorporating non-constant gauge field strength as an external background coupled to the boundary of a string worldsheet in bosonic string…

### BPS D-branes on Non-supersymmetric Cycles

- Mathematics, Physics

In certain regions of the moduli space of K3 and Calabi-Yau manifolds, D-branes wrapped on non-supersymmetric cycles may give rise to stable configurations. We show that in the orbifold limit, some…
