Superstring D-Branestudy the physics of these BPS objects from many complementary viewpoints: the spacetime perspective, the world-sheet theory, and the QFT on the branes. We describe the geometry of the BPS objects and outline the relation with YM instanton and their ADHM construction

Spectrum, Vertices, and BRST Quantizationral properties of perturbative (super)string theory. In the three preliminary sections we discuss subtle points of bosonization, light-cone quantization, and the old covariant quantization. In the last section, the Chan–Paton degrees of freedom are introduced and studied.

Calabi–Yau Compactificationsaiming to be didactical but also mathematically precise and self-contained. We review all geometry we need. One may study these vacua from three viewpoints: . These three approaches, despite the difference of languages, perspectives, and tools, turn out to be essentially equivalent [.].
