## Applied Mathematics Seminars

### Autumn 2014

All seminars (unless otherwise stated) will take place on **Tuesdays at
3.00pm in ****Drayton B20 Jevons LT **which is located in Drayton House (30 Gordon Street). See the **link to the map for Drayton House** for further details. There will be tea afterwards in Room 606 in the Mathematics Department (25 Gordon Street, across the street from Drayton House) - see how to find us for further details. If
you require any more information on the Applied seminars please
contact Prof Slava Kurylev e-mail: y.kurylev AT ucl.ac.uk or
tel:
020-7679-7896.

### 7 October 2014

Dr G El - University of Loughborough

###### Title: Soliton gas and soliton turbulence in integrable systems

Abstract:

A linear operator pencil P(lambda)=A-lambda B, with self-adjoint
coefficients A and B, may have a complicated spectral picture if both operators
A, B are sign-indefinite. I will discuss (up to) three examples - a matrix
pencil with a very simple structure studied jointly with E B Davies, a simple
ODE pencil (joint work in progress with M Seri), and a problem involving a
Dirac operator (joint work with D M Elton and I Polterovich) which illustrate
some interesting and not yet fully understood phenomena and pose a number of
open questions.

### 14 October 2014

coefficients A and B, may have a complicated spectral picture if both operators

### 21 October 2014

Prof Carol Alexander - University of Sussex

###### Title: Discretization-Invariant Swaps

Abstract:

### 28 October 2014

Prof Geoff Vallis - University of Exeter

###### Title: Some GFD Problems in Global Warming

Abstract:

I will discuss a few problems in Geophysical
Fluid Dynamics that arise when considering a planetary atmosphere that is
warming. These include the increase in height of the tropopause, the expansion
of the Hadley Cell, and a shift in the mid-latitude jets.

### 25 November 2014 - COLLOQUIUM TALK

Prof Beatrice Pelloni - University of Reading
