The mathematics of Ponzi schemes [PDF]

open access: greenMathematical Social Sciences, 2009
A flrst order linear difierential equation is used to describe the dynamics of an investment fund that promises more than it can deliver, also known as a Ponzi scheme. The model is based on a promised, unrealistic interest rate; on the actual, realized nominal interest rate; on the rate at which new deposits are accumulated and on the withdrawal rate ...

A mathematical analysis of the cumulus pricing scheme [PDF]

open access: greenComputer Networks, 2005
One important task in current and future communication networks is to define a suitable pricing scheme. It is then preferable to formulate a mathematical model, so that parameters will be optimized and important properties such as fairness or truthful anticipated load revelation (or incentive compatibility) will be verified.

Description Schemes for Mathematical Web Services [PDF]

open access: hybridElectronic Workshops in Computing, 2002
While commodity technologies are now available for deploying and accessing web (and grid) services, the issue of how a potential user discovers a service which matches his or her requirements is still open. This paper looks at the specific case of mathematical web services and proposes two complementary solutions to this problem.

The GAMS classification scheme for mathematical and statistical software [PDF]

open access: hybridACM SIGNUM Newsletter, 1983
An extensive tree-structured problem-oriented scheme for classifying mathematical and statistical software is presented. The scheme is a substantially modified version of a scheme proposed by Bolstad, which was based on the widely-used SHARE system. It is an attempt to reflect more accurately the current state of mathematical and statistical software ...
