are investigated.Comment: LaTeX v1.2, 10 pages with no figur
-covariant Oscillators and q-Deformed Quantum Mechanics in n Dimensions
In this paper the coherent state for -covariant oscillators is
constructed and is shown to satisfy the completeness relation. And the
q-analogue of quantum mechanics in n dimensions is obtained by using
oscillators.Comment: LaTeX v1.2, 10 pages with no figur
Expanders are counterexamples to the coarse -Baum-Connes conjecture
We show that certain expanders are counterexamples to the coarse

On the Exceptional Gauged WZW Theories
We consider two different versions of gauged WZW theories with the
exceptional groups and gauged with any of theirs null subgroups. By
constructing suitable automorphism, we establish the equivalence of these two
theories. On the other hand our automorphism, relates the two dual irreducible
Riemannian globally symmetric spaces with different characters based on the
corresponding exceptional Lie groups.Comment: 5 pages, LaTeX fil
Business integration models in the context of web services.
E-commerce development and applications have
been bringing the Internet to business and marketing
and reforming our current business styles and
processes. The rapid development of the Web, in
particular, the introduction of the semantic web and
web service technologies, enables business
processes, modeling and management to enter an
entirely new stage. Traditional web based business
data and transactions can now be analyzed,
extracted and modeled to discover new business
rules and to form new business strategies, let alone
mining the business data in order to classify
customers or products. In this paper, we investigate
and analyze the business integration models in the
context of web services using a micro-payment
system because a micro-payment system is
considered to be a service intensive activity, where
many payment tasks involve different forms of
services, such as payment method selection for
buyers, security support software, product price
comparison, etc. We will use the micro-payment case
to discuss and illustrate how the web services
approaches support and transform the business
process and integration model.
