## Mesh generation and preliminary Findif calculations for limiter W7-X configuration »

Grzegorz Pełka, Institute of Plasma Physics and Laser Microfusion (IPPLM), Warsaw, Poland
4pm 21 October 2019

Findif is a 3-D finite difference, multi-fluid code devised mainly for edge plasma simulations. Intrinsically and irreducibly 3-dimensional problems, such as stellarator or ergodic divertor simulations, are a natural playground for Findif.

## On Escobar's conjecture and related topic »

Dr. Changwei Xiong, ANU
2pm 15 October 2019

The fundamental gap conjecture for Dirichlet eigenvalue problem on Euclidean domains is a well-known conjecture. In this talk we shall present our progress on Escobar's conjecture, namely, we confirm it for a large class of Riemannian manifolds, including Euclidean domains.

Dr Lindon Roberts, ANU
4pm 14 October 2019

In this talk, I will introduce DFO methods and recent progress in the theory and implementation of these methods, with a particular focus on least-squares problems (e.g. parameter fitting).

Dr. Haodi Chen, ANU
2pm 11 October 2019

In this talk we will discuss the a priori estimates for some Monge-Amp\ere type equation and their applications.
