delta | float[dimensionless scalar variable] |
In renormalization theory based upon a non-interacting polymer,
appears to approach a value of
. For interacting
polymers, the matter is not so clear-cut, but one probably should not
exceed
by much since the exponent has the tendency to "damp out"
the correlation. There is little meaning in a correlation of less than
exponential square root as might be attributed to a spin-glass system
or some forms of neural networks. Therefore, the value for
has been set to the limits
.
