Title: A Walking Tour of Geometric Inverse Problems


Abstract: Inverse problems are a mathematical formulation of questions which appear ubiquitously throughout nature. The main objetive of an inverse problem is to derive model parameters given observational data. Imaging problems, in which the attenuation of a signal beamed through a medium is used to determine the parameters pertaining to the properties of the medium are examples of inverse problems. Within this talk, the mathematical machinery behind some of these problems will be described and used to formulate the Geodesic X-ray tomography problem on simple Riemannian manifolds of dimension 2.



Graduate Talks in Geometry and Topology, (GT)^2, is an online symposium organised by and for graduate students, running fortnightly throughout 2021 and 2022. The symposium is designed to provide an opportunity for Australian graduate students in geometry and topology to present their research to a diverse audience, as well as engage, network, and share ideas with other students in their field.

Supported by MATRIX and AMSI.

Statement of Inclusiveness

This will all be in an inclusive, supportive environment that assumes only undergraduate-level mathematical knowledge. We endorse this statement of inclusiveness:

We are a group of scholars, researchers, and teachers. We refuse to compromise the ideals of academic freedom and open exchange. We affirm that scientific events have to be open to everybody, regardless of race, sex, religion, national origin, sexual orientation, gender identity, disability, age, pregnancy, immigration status, or any other aspect of identity. We believe that such events have to be supportive, inclusive, and safe environments for all participants. We believe that all participants are to be treated with dignity and respect. Discrimination and harassment cannot be tolerated. We are committed to ensuring that the scientific events in which we participate follow these principles, and we request that organizers of scientific events make explicit statements on the event website to that effect.

We acknowledge the Traditional Owners of the land on which we work and live, and pay our respects to Elders past and present. We celebrate the stories, culture and traditions of Aboriginal and Torres Strait Islander Elders of all communities who also work and live on this land.
