ActiveMath is a generic webbased learning system that dynamically generates interactive (mathematical) courses adapted to the students goals, preferences, capabilities, and knowledge. The content is represented in an semantic xmlbased format. For each user, the appropriate content is retrieved from a knowledge base and the course is generated individually according to pedagogical rules. Then the course is presented to the user via a standard webbrowser. One of the exceptional features of ActiveMath is its integration of standalone mathematical service systems. This offers the means for exploratory learning, realistically complex exercises as well as for learning proof methods. The article provides a comprehensive account of the current version of ActiveMath.

In this paper we present an extension OMDoc to the OpenMath standard that allows to represent the semantics and structure of various kinds of mathematical documents, including articles, textbooks, interactive books, courses. It can serve as the content language for agent communication of mathematical services on a mathematical software bus.

The OpenMath framework for transmitting mathematical objects over the Internet relies on the concept of Content Dictionaries (CDs) to define the semantics of mathematical objects. This is an essential measure for establishing a meaningful communication amongst mathematical software systems (and humans). Currently, the infrastructure for conceiving, administering, viewing CDs is limited to a filebased almost flat repository. In this paper, we propose to use the OMDoc extension of the OpenMath Xml encoding as an infrastructure to express and manipulate content dictionary information. OMDoc extends OpenMath by adding support for document markup (making the CDs more readable to the human user) and structured specification (making them more explicit, formal, and allow the user to reuse, and inherit CD information in a flexible, but welldefined way).

Gerard Debreu symbolizes the use of a new mathematical apparatus, an apparatus comprehended by most economists only abstractly. Nevertheless, his work has given us an improved intuitive understanding of the underlying economic relevance. His clarity and analytical rigor, as well as the distinction drawn by him between an economic theory and its interpretation, have given his work important bearing on the choice of methods and analytical techniques within economic theory on a par with any other living economist. —Introduction of the Nobel laureate at the Royal Swedish Academy of Sciences, 1983 The complexity of an economy stands in sharp contrast to the simplicity of a question that must be raised about its operation. Many agents compose the economy, and they have to deal with a large number of commod
