In advanced physics there are applications such as string theory, D-brane
theory and condensed matter physics.
gauge theories from toric singularities and toric duality.
An introduction to string theory and D-brane
dynamics; with problems and solutions, 2d ed.
Other contributors highlight the scientific opportunities offered by a high energy electron-ion collider, construct a little Higgs theory, introduce intersecting D-brane
models, and explore the hypothesis that the generation of a primordial lepton-antilepton asymmetry (Leptogenesis) is the origin of matter.
Among the topics are D-branes
and K-theory in two-dimensional topological field theory, open strings and Dirichlet branes, metric aspects of Calabi-Yau manifolds, and the mathematics of homological mirror symmetry.
