We review some results about the first eigenvalue of the infinity Laplacian operator and its first eigenfunctions in a general norm context. Those results are obtained in collaboration with several authors: V. Ferone, P. Juutinen and B. Kawohl (see [BFK], [BK1], [BJK] and [BK2]). In section 5 we make some remarks on the simplicity of the first eigenvalue of ∆∞: this will be the object of a join...

the increasing amount of scientific collaboration has led to an increase  in the quality of scientific publications. the goal of this article is to analyze the co-authorship patterns and networks in sbums’s scientific publications in wos from 2009 to 2013. hence, the co-authorship indicators and ratio of national to international collaborations are determined. this research is a descriptive sur...

lace expansion and suggesting that it might converge in five dimensions, and to Takashi Hara for the pleasure of four years of collaboration and for permission to include unpublished joint work. We gratefully acknowledge financial support from the Natural Sciences and Engineering Reearch Council of Canada. Finally we offer our thanks and deep appreciation to Joyce Kruskal and Joanne Nakonechny ...

This book gathers together our joint work (through 2008) on the closely connected topics of repeated games and reputation effects, along with related papers on more general issues in game theory and dynamic games. Since this work studies, among other things, the way that long-run interactions facilitate cooperation, and our collaboration began in 1980, it seems fitting that the papers appear in...

At the NIST March 2010 workshop on “The Future of NFIQ”, the development of a new (open source) version of NFIQ in consultation and collaboration with users and industry was recommended. Following this recommendation, NIST and BSI set up a joint project for the development of a successor version of NFIQ. This paper explains the reasons and needs for the development and details the planned appro...

Regional economic integration is the development trend of market economy. Beijing, Tianjin and Hebei Metropolitan Circle has great development potential, and therefore, bringing their industrial advantages into full play and realizing the coordinated development of three industries, play very important role in promoting the economic development of this area. This paper analyzes the necessity of...

Computational Aesthetics draws from both a long history of artistic expression and the possibilities that computational methods can provide. As such, its success depends on a dialogue between the arts world and computer science. Based on the experience we gained through an art-computer science joint project on non-repetitive patterns we attempt to document our personal dialogue, to analyze the ...

This publication is the result of a close collaboration between three Services of the European Commission DG AGRI, EUROSTAT and the Joint Research Centre (Ispra) and the European Environmental Agency. It presents work carried out by the different teams based on the CORINE Land Cover inventory. The different articles seek to systematically explore the potential and limits of this tool as a contr...
