We address the problem of integrating classes that are developed independently. We propose to factorise the intensional and extensional dimensions of classes and let them be organised in separate hierarchies. Class integration becomes the problem of integrating extent graphs, and to describe relations between the properties of the classes to be integrated. Our approach may be seen as extending ...

Providing the solution to the debt and deficit problems of developed economies is too big a task. I doubt it is possible to offer general recipes that can apply to all industrial countries, despite the surprisingly common origins of the deficit problems documented by the Mussa and Masson paper in this conference. For example, while in most countries accumulated social security liabilities repre...

In structuring this conference, the organizers have made the sensible decision to devote separate sessions to the problems of developing and developed countries. When attempting to confront unsustainable fiscal policies, developed economies are relieved of many of the economic constraints with which developing countries must deal. With greater wealth, more stable and credible governments, and m...

Superfluid turbulence is governed by two dimensionless parameters. One of them is the intrinsic parameter q which characterizes the relative value of the friction force acting on a vortex with respect to the non-dissipative forces. The inverse parameter q−1 plays the same role as the Reynolds number Re = UR/ν in classical hydrodynamics. It marks the transition between the ”laminar” and turbulen...

A weighing matrix is a square matrix whose entries are 1, 0 or −1, such that the matrix times its transpose is some integer multiple of the identity matrix. We examine the case where these matrices are said to be developed by an abelian group. Through a combination of extending previous results and by giving explicit constructions we will answer the question of existence for 318 such matrices o...
