MoCaO lectures 2025: August 25-29 (zoom).

The MoCaO Lecture Series will run daily from 25–29 August, from 11:00 AM to 12:00 PM AEST.

Speakers

Professor Tim Moroney is Professor in Applied and Computational Mathematics within QUT’s School of Mathematical Sciences. Among all the topics that have played a role throughout his research career, the one that features most prominently is numerical linear algebra, and particularly methods for sparse matrices. His current research interests come from various applications across water waves, droplets, surface reconstruction, moving interface problems, and fractional calculus.

Dr Qianqian Yang is a Senior Lecturer in Applied and Computational Mathematics within QUT’s School of Mathematical Sciences. Qianqian has extensive experience in developing computationally efficient methods for solving fractional order partial differential equations. With this background, her recent research interest lies in the application of these fractional calculus models to real-world problems, especially in the area of combining numerical simulations, fractional order models and magnetic resonance imaging (MRI) to probe in vivo brain tissue microstructure.

Abstract

This series of lectures will introduce the theoretical and practical ideas for iterative methods applied to sparse matrices. Sparse matrices arise in many applications across science, engineering, statistics, business and beyond. Iterative methods that exploit the sparsity of these matrices are essential for overcoming the scaling on storage and floating-point calculations that otherwise renders problems even of modest dimensionality impractical to solve.

A remarkably versatile family of numerical methods called Krylov subspace methods can be applied to a wide class of sparse matrix problems. In doing so, they impose only minimal requirements on the means by which a matrix is utilised, paving the way for many of today’s high-performance codes. This course covers Krylov subspace methods for two common problems: eigenvalue problems and linear systems, from their derivation through to efficient numerical implementation.

The lectures will be running in zoom.

MOCAO lectures: A/Prof Vera Roshchina, UNSW

Lectures on Convex Geometry

A/Prof Vera Roshchina, UNSW.

Monday, July, 15-Wednesday, July, 17, 11AM each day (AEST)

We go over the basics of facial structure of convex sets, starting with the finite dimensional setting. We review the tools that help study geometric properties of convex sets and to construct convex sets with desirable properties. We then focus on structured convex problems, predominantly those defined algebraically (through matrix and polynomial inequalities and representations). Finally, we review some properties and behaviours of convex sets that are specific to the infinite-dimensional setting. The fundamental mathematical ideas and phenomena will be contextualised in optimisation applications, including conic programming and projection methods.

MoCaO Lectures:  Geometry and Convexity in Optimisation

 July 15-19, 2024

We are pleased to announce the 2024 MoCaO Lectures in Computation and Optimisation. For 2024 we
are focusing on Geometry and Convexity in Computation. These one-hour lectures will be held each day, and all lectures will be broadcast via Zoom.

July 15-19, 2024, 11-12 am AEST (GMT+10) each day

This series of lectures will introduce the theoretical tools and notions of convex geometry that stem from or are applicable to the problems of modern convex optimisation. The lectures will cover the facial structure of general and structured convex set in Euclidean spaces, as well as in general vector spaces. These lectures are designed to be accessible to novices to the field who have a mathematics and computational background, such as PhD students, postdoc and/or inquisitive academics who wish to have a better understanding of recent advances in this dynamic field. These lectures will be given online via
Zoom. Please read the notice below regarding the registration to obtain the Zoom link.

Summary: Convex geometry is a fascinating area of simplicity and elegance yet mathematically rich. It is home to many beautiful and surprising theorems with numerous applications ranging from optimisation practical ones such as robotics, economics, and machine learning. In these year’s lectures, we go over the basics of facial structure of convex sets, starting with the finite dimensional setting. We review the tools that help study geometric properties of convex sets and to construct convex sets with desirable properties. We then focus on structured convex problems, predominantly those defined algebraically (through matrix and polynomial inequalities and representations). Finally, we review some properties and behaviours of convex sets that are specific to the infinite-dimensional setting. The fundamental mathematical ideas and phenomena will be contextualised in optimisation applications, including conic programming and projection methods.
