A Generalized Duality Symmetry for Nonabelian Yang-Mills Fields
Chan Hong-Mo, J. Faridani, Tsou Sheung Tsun
It is shown that classical nonsupersymmetric Yang-Mills theory in 4 dimensions is symmetric under a generalized dual transform which reduces to the usual dual *-operation for elect…
How Filaments are Woven into the Cosmic Web
J. Richard Bond, Lev Kofman, Dmitri Pogosyan
Observations indicate galaxies are distributed in a filament-dominated web-like structure. Numerical experiments at high and low redshift of viable structure formation theories als…
Unbiased Cluster Lens Reconstruction
Gordon Squires, Nick Kaiser
Weak lensing observations measure the shear field and hence the gradient of the dimensionless surface density . We present several new algorithms to recover {}from shear est…
Lattice Gas Automata for Reactive Systems
Jean Pierre Boon, David Dab, Raymond Kapral +1
Reactive lattice gas automata provide a microscopic approachto the dynamics of spatially-distributed reacting systems. After introducing the subject within the wider framework of l…
Are Four-Fermion Operators Relevant for the Fermion Mass Problem?
B. Holdom
Four-fermion operators may have large anomalous scaling and become relevant operators in some strongly interacting gauge theories. We present a detailed model which illustrates som…
The Average Mass-to-Light Profile of Galaxy Clusters
R. G. Carlberg, H. K. C. Yee, E. Ellingson
The systematic errors in the virial mass-to-light ratio, M_v/L, of galaxy clusters as an estimator of the field M/L value are assessed. We overlay 14 clusters in redshift space to…
