摘要:
AbstractWe discuss spontaneous supersymmetry breaking inN= 2 globally supersymmetric theories describing a system of abelian vector multiplets. The most general form of the action admits, in addition to the usual Fayet‐Iliopoulos term, a magnetic Fayet‐Iliopoulos term for the auxiliary components of dual vector multiplets. In a generic case, this leads to a spontaneous breakdown of one of the two supersymmetries. In some cases however, dyon condensation restoresN= 2 SUSY vacuum. This talk is based on the work done in collaboration with H. Partouche,

摘要:
AbstractIn this lecture we review some contributions to the study of dynamical questions inN= 2 supersymmetric string compactifications. The recurrent themes are the relation between perturbative heterotic couplings, expressed in terms of certain modular forms, and the corresponding type II couplings, determined by genusginstanton numbers. The investigation is performed concentrating on theN= 2 prepotential and on the gravitational couplingF1, for a particular heterotic/type II dual string pair. The relation to theN= 4 situation is also briefly discussed.

摘要:
AbstractWe review some recent results on the sigma‐model properties of the scalar manifold ofN= 2 theory, specifically the symplectic structure of special geometry. As a consequence we derive sum rules for the physical charges of the vector multiplets and their interpretation in terms of the cohomology of a Calabi‐Yau threefold. A discussion of the general properties of the scalar potential is also gi

摘要:
AbstractWe study the symplectic reparametrizations that are possible for theories ofN= 2 supersymmetric vector multiplets in the presence of a chiral background and discuss some of their consequences. One of them concerns an anomaly arising from a conflict between symplectic covariance and holomorphy.

摘要:
AbstractString duality suggests a fascinating juxtoposition of world‐volume and target‐space dynamics. This is particularly apparent in theD‐brane description of stringy solitons that forms a major focus of this article (which isnotintended to be a comprehensive review of this extensive and sophisticated subject). The article is divided into four sections:• The oligarchy of string world‐sheets•p‐branes and world‐volumes• World‐sheets for world‐volumes• Boundary states,D‐branes an

摘要:
AbstractOpen descendants extend Conformal Field Theory to unoriented surfaces with boundaries. The construction rests on two types of generalizations of the fusion algebra. The first is needed even in the relatively simple case of diagonal models. It leads to a new tensor that satisfies the fusion algebra, but whose entries are signed integers. The second is needed when dealing with non‐diagonal models, where Cardy's ansatz does not apply. It leads to a new tensor with positive integer entries, that satisfies a set of polynomial equations and encodes the classification of the allowed boundary operator
