In particular, a hyperbolic 3\u2013manifold with finitely generated fundamental group is uniquely determined by its topological type and its end invariants\u2014geometric data encoded by the ending laminations on its boundary [1]. Both compressible and incompressible boundaries can occur. However, in the compressible case\u2014when a surface bounds a handlebody\u2014not every lamination can arise as an ending lamination; only those that are incompressible can.\r\n\r\nThis phenomenon was studied by Masur and Kerckhoff in the 1980s, who showed that the mapping class group of a handlebody acts properly discontinuously on an open subset of the space of projective measured laminations [2]. This open set, known as the Masur domain, has full measure with respect to the Thurston measure and consists entirely of incompressible laminations [3]. In this talk, we follow Masur and Kerckhoff\u2019s approach to reproduce this result. Also, we will see that it contains a beautiful application of train track theory.\r\n\r\nReference:\r\n[1] J. F.

However, standard methods come with many challenges in medical and scientific applications: they are computationally expensive, they require lots of training data, and they may not be robust to distribution shifts between the training data and the test data. This talk will describe methods for tackling these challenges, focusing on medical imaging inverse problems like MRI and low-dose Xray CT image reconstruction.
