Renormalization of polymer chain conformations in momentum space

Renormalization of polymer chain conformations in momentum space 

The chief significance in this approach is placed upon calculation of the distribution function 6 h at a fixed end-to-end vector (Equation 5.1-85) and at an additional fixing of a point in.sidc the chain (Equation 5.1-118). Using the Fourier transform 

As discussed above, the m2w ro.scopic properties of a system (in this ceise, /t ) iiiu.st not depend on line-scaled details. When Equation 4 is calculated on the basis of llainilto-nian 5.1 -62, divergences arise due to the fine details. To eliminate them, a renormalization procedure is required. 

The arbitrariness of the scale length L leads to the arbitrariness in the numerical values of the final quantities, which remain even on elimination of singularities. I liis arbitrarine.ss is eliminated by correlation of theory with experimental quantities (Oono and Freed, 1982).
