The Renormalization Group and the Dynamics of Genetic Systems
Christopher R. Stephens
In this brief article I show how the notion of coarse graining and the Renormalization Group enter naturally in the dynamics of genetic systems, in particular in the presence of re…
Dimensional Crossover in the Non-Linear Sigma Model
Denjoe O'Connor, C. R. Stephens, J. A. Santiago
We consider dimensional crossover for an O(N) model on a d-dimensional layered geometry of thickness L, in the sigma-model limit, using ``environmentally friendly'' renormalization…
Schemata as Building Blocks: Does Size Matter?
C. R. Stephens, H. Waelbroeck, R. Aguirre
We analyze the schema theorem and the building block hypothesis using a recently derived, exact schemata evolution equation. We derive a new schema theorem based on the concept of…
Schemata Evolution and Building Blocks
C. R. Stephens, H. Waelbroeck
In the light of a recently derived evolution equation for genetic algorithms we consider the schema theorem and the building block hypothesis. We derive a schema theorem based on t…
Universal Scaling Properties of Superconductors in Magnetic Fields
Denjoe O'Connor, C. R. Stephens
Based on renormalization group arguments we establish that for a superconductor in the presence of a weak external magnetic field, , the dependence on and the deviation from…
Boson Mapping in Field Theory
P. O. Hess, J. C. López Vieyra, C. R. Stephens
A boson mapping of pair field operators is presented. The mapping preserves all hermiticity properties and the Poisson bracket relations between fields and momenta. The most practi…
