Basics of Geometry of Complex Manifolds,st, we introduce the definition of complex manifolds and holomorphic vector bundles on complex manifolds. We also discuss Chern classes of holomorphic vector bundles. Then we introduce K.hler manifolds, which play a central role in geometry of complex manifolds, and explain various characteristics o

Topological Sigma Models,f topological field theory. There are two types of topological sigma models, both of which are obtained from the . supersymmetric sigma model through an operation called “topological twist”. This distinction comes from the differences in the topological twist. We call these two types A-model and B-m

Direct Marketing Based on a Distributed Intelligent Systemerarchy Process. A Multi Agent System is used to support the definition of survey parameters, the survey itself and the intelligent processing of clients’ judgements. Clusters are synthesized after processing customers preferences and they represent a useful tool to analyze their preferences towards products’ features.
