Advanced studies

The course is intended for undergraduate students of mathematics, physics and chemistry

and mathematical biology. Prior courses in advanced calculus and linear algebra are required

(Analyysi I+II, Vektorianalyysi and Lineaarialgebra 1, or Mapu 1-2).

The scope of the course is to give a practical introduction to methods of perturbation theory

of wide use in theoretical and mathematical physics and mathematical biology. In order to

illustrate the use of these techniques the second part of the course will focus on specific

problems discussed in recent research papers.

Weeks 36-42 and 44-50, Tuesday 14-16 in room C123. Two hours of exercise classes per week.

Notice: last two lectures

Friday 02.12 at 14-16 in C123

Friday 09.12 at 14-16 in B321

Exam projects can be based on research articles using multi-scale perturbation theory. Besides those available from Pavliotis's

web-page, research articles of interest may be:

- M. Vergassola and M. Avellaneda, Scalar Transport in Compressible Flow, Physica D, 106 (1997) 148-166 arXiv:chao-dyn/9612001
- A. Mazzino, S. Musacchio, A. Vulpiani, Multiple-scale analysis and renormalization for pre-asymptotic scalar transport,

Phys. Rev. E 71, 011113 (2005), arXiv:nlin/0412004. - L. Biferale, A. Crisanti, M. Vergassola, A. Vulpiani, Eddy diffusivities in scalar transport, Phys. Fluids 7, 2725 (1995), cond-mat/9412115
- Avellaneda, M. & Majda, A. J. An integral representation and bounds on the effective diffusivity in passive advection by laminar and turbulent flows Com. Math. Phys., 1991, 138, 339-391

The lecture notes cover and sometimes integrate the material expounded in the lections. They also give bibliographic references for the same topics.
