This study group has the aim to make the PhD students in Analysis to meet and talk about math together, everybody is welcome. The study group usually meets on** friday afternoon at 2PM in various rooms**. There is a mailing list you can join by asking me at __florent.noisette@math.u-bordeaux.fr__.

Format : the lecturer assumes that the attendees have at least skimmed through the material he/she is supposed to present. The talk is usually between one and two hour long, and can be divided in several sessions if needed.

If you attend the study group and you believe that there is a permanent member of the team who could provide interesting insight about the next lecture topic, you can ask them during Tuesday's team seminar.

For the permanents members of the team : the study group welcomes any suggestion for a presentation on the topic of the current/past/future lectures, or on something you believe could be of interest to us. Please contact me if you have any idea of such a talk.

**Ideas of subjects :**

- Kolmogorov's turbulence theory and/or oceanography related topics : Batchelor's book on homogeneous turbulence; Hasselmann's book on ocean waves; Zakharov's book on turbulence
- kinetic equations theory, for example with kinetic schemes in numerical analysis : Godlewski's & raviart's book
- physics session on Schrodinger : microscopic mode, potential wells, hydrogen model and atom interactions
- equations of general relativity : Maxwell, Lorentzian change of variable, Ricatti equation
