Topology and the axial anomaly in abelian lattice gauge theories Martin Lüscher
The axial anomaly in abelian lattice gauge theories is shown to be equal to a simple quadratic expression in the gauge field tensor plus a removable divergence term if the lattice Dirac operator satisfies the Ginsparg-Wilson relation. The theorem is a consequence of the locality, the gauge invariance and the topological nature of the anomaly and does not refer to any other properties of the lat...

Oxidative stress affects the availability of key-regulators of vascular homeostasis and controls a number of signaling pathways relevant to myocardial and vascular disease. Reactive oxygen species are generated by different intracellular molecular pathways principally located in mitochondria. The notion that mice carrying a targeted mutation of the p66 gene display prolonged lifespan, reduced p...

Tunisia’s unemployment rate has been among the highest in the world for almost two decades. This article claims that such a high rate reflects measurement problems rather than labor market inefficiency. After discussing the reasons why unemployment rates may not be comparable across countries and reviewing the tools that are available to analyze unemployment in a specific country, the article p...

The focus of my research is extremal graph theory and random combinatorial structures. I have also worked in a variety of other areas, including intersecting hypergraphs, the theory of positional games and Ramsey theory. Combinatorics, and particularly graph theory, has a wide variety of applications. My own research in the edit distance of graphs has applications in biology and computer scienc...

Bill Martin studied biology at Texas A&M and the University of Hannover. He did his PhD at the Max-Planck Institute for Breeding Research in Cologne under the generous supervision of Heinz Saedler, who discovered the transposons known as IS elements. After fi nishing his PhD in 1988, he did his postdoctoral work on chloroplastcytosol isoenzymes, endosymbiosis, and gene transfer at the Universit...
