AARMS Geophysical Inverse Problems Discussion Series
Zhang et al., 2022, Geophysical inversions on unstructured meshes using non-gradient based regularization The paper above, the main one we will discuss, seeks to improve upon the method in the paper below, which increases some computational demands. We'd like to better understand how well the paper above improves upon: Lelievre et al., 2013, Gradient and smoothness regularization operators for geophysical inversion on unstructured meshes.

This series of annual meetings focusses on recent advances in all aspects of classical and quantum gravity. Topics include mathematical general relativity, relativistic astrophysics, gravitational waves, cosmology, gravitational aspects of string theory, loop quantum gravity, and numerical relativity. There is particular focus on the development of graduate students and postdoctoral fellows. As in previous years, there is a two day workshop during which three invited experts (from outside the Atlantic region) give introductory lectures aimed on current topics of high…

Combinatorial algebra and algebraic combinatorics are two highly active areas of research. Their importance is felt throughout theoretical and applied mathematics, including algebraic geometry, representation theory, commutative algebra, and mathematical physics; they have found numerous practical applications in diverse fields. The connections between these overlapping subjects are central to the CAAC workshops' traditional thematic goals. They were emphasized in a series of expository lectures which were given by Tony Geramita and Fran\c{c}ois Bergeron in January 2004 at Queen's University. Through…

Farquharson, 2008, Constructing piecewise-constant models in multidimensional minimum-structure inversions. Also available on the author's webpage: https://www.esd.mun.ca/~farq/special.html Considering the discussion at our previous meeting, it seems natural to next look at methods for recovering sharp/blocky/compact features. This one is a relatively short paper, going back to a time when most inversion work was on rectilinear meshes, and it would be sensible to return to these ideas now that unstructured meshes are seeing more use.

The aim of this workshop is to discuss the current state of research in several interrelated areas of algebra. The first three workshops with the same title were held on the St. John's campus of Memorial University (MUN) in 2001 and at the Bonne Bay Marine Station of MUN in Gros Morne National Park in 2007 and 2012. The current workshop is organized by the Atlantic Algebra Centre (AAC) of MUN in the framework of the collaborative research group "Groups,…

Combinatorial design theory has a history dating back to the 18th century when Leonhard Euler pondered the existence of orthogonal pairs of Latin squares. This session will showcase recent results in topics such as classical designs, cycle systems, graph decompositions, Latin squares and other aspects of design theory by bringing together leading and emerging researchers in the field to share their recent results, techniques, and applications.
