Mr Christopher Dimech, from the Department of Geosciences, in collaboration with the Department of Mathematics,  will present the second talk entitled 'Geomathematics and Computation' as part of the series Christopher Dimech Talks, taking place at Room 405, Mathematics and Physics Building, University of Malta Msida Campus on 7 March from 09:00 to 10:00.
  
  The Geomathematics Seminar is inspired by the official launch of the GNU Behistun Package in February 2017, and later announced in Issue 107 of the Free Software Foundation鈥檚 (FSF) monthly news digest and action
  update. Published in English, Spanish, Brazilian Portuguese, and French, the Free Software Supporter attracts a readership of 195,394. The Free Software Movement campaigns to win for the users of computing the freedom that comes from free software. Free software puts its users in control of their own computing. Nonfree software puts its users under the power of the software's developer or of the copyright holder. The Free Software Foundation is the organisational sponsor of the GNU Project, providing funding and promoting important free software development. In addition, the FSF provides development systems for GNU software maintainers and administrators.
  GNU Behistun has proposed two projects for the 2019 Google Summer of Code, open to university students, age 18 and older in most countries. In this talk, Christopher Dimech, the Chief Administrator of GNU Behistun, will discuss the formulation of Geophysical Inverse Problems and the task of reconstructing initial geological configurations from their geological responses, the latter being very much what geology is about.
  In the wide sense, the ideas raised by Inverse Problems are considered the most difficult computational problems in mathematics. So the progress in the mathematical methods solving these problems are very profound and therefore have enormous impact in many areas. Consequently, Christopher Dimech will then detail a number of mathematical frameworks and strategies for computation that are raised by Indirect Imaging Conundra. The computational topics for discussion will cover the broad expanse of computational schemes for ill-posed problems, starting from regularisation and preconditioning techniques to Bayesian Inference Techniques that allow the complete description of every subsurface parameter as a probability distribution.
