1402 NOTICES OF THE AMS VOLUME 50, NUMBER 11 Energized by the success of wavelets, the last two decades saw the rapid development of a new field, computational harmonic analysis, which aims to develop new systems for effectively representing phenomena of scientific interest. The curvelet transform is a recent addition to the family of mathematical tools this community enthusiastically builds up...

This paper presents the analysis of an improved distributed checkpointing algorithm. It shows that the message volume of Koo and Toueg's distributed checkpointing algorithm approaches 3f N for large checkpoint intervals where N is the number of processes and processes randomly send messages to f other processes. Thus, the average mesage volume is O(n^2). We show how Koo and Toueg's algorithm ca...

In a previous lecture, we defined the Byzantine agreement/broadcast problems and showed that there is no protocol solving these problems when the fraction of corrupted players is 1/3 or larger. Today, we prove the converse by showing a protocol for broadcast (and hence Byzantine agreement; cf. the previous lecture) when the fraction of corrupted players is less than 1/3. The protocol we will sh...

Emmanuel Boucrot obtained an undergraduate and a master's degree in biochemistry at the University of Geneva in Switzerland. He pursued his PhD in immunology at the University of Aix-Marseille II in France, supervised by Stéphane Méresse in the laboratory of Jean-Pierre Gorvel. Emmanuel moved to the USA for his postdoctoral training in the laboratory of Tomas Kirchhausen at Harvard Medical Scho...
