is independent of both the segments indices and the starting position. Hence,

The eqn. 8.5 is solved using Fourier transform and the boundary condition, p₀(^r, 0) =

J(r), to obtain

p₀(R, N) = [3∕(27γ≡²)]^3/2 exp [-3∣R∣²∕(2≡²)] ,            (8.7)

where R is the end-to-end vector of the chain, R = rjv - r₀.

In SCFT, an elegant and particularly convenient continuous Gaussian chain model
is employed. This model is the continuum limit of the discrete Gaussian chain model
in which the polymer chain is viewed as a continuous, linearly elastic filament. The
configuration of the chain is specified by a space curve r(s) where s ∈ [0, N], as shown
in fig. 8. lb. The continuous variable s describes the locations of a segment along the
backbone of the chain. The potential energy of the continuous Gaussian chain can
be written as

while the partition function is given by
