Scaling limits of selfinteracting walks and diffusions with long memory
Lectures at the Prague Summer School on Mathematical Physics  2011
Prague, August 29September 4, 2011
See my Chorin lecture notes
Here are some notes about AlderWainwright scaling argument
Here are some notes about Gaussian Hilbert spaces (or Fock spaces), Wick polynomials, etc
And some recent papers related to the topics of the course:

Illés Horváth, Bálint Tóth, Bálint Vető:
Diffusive limits for "true" (or myopic) selfavoiding random walks and selfrepellent
Brownian polymers in three and more dimensions
Probability Theory and Related Fields (2011+)
