Topic: “Reassembly and analysis of broken objects”
Abstract: The problem of analyzing and reassembling broken objects appears in a broad range of applications, including jigsaw puzzle assembly, archaeology (broken pots and statues), surgery (broken bones and reassembly of histological sections), paleontology (broken fossils and egg shells), and anthropology (broken bones and lithics). I will discuss recent progress on such problems based on new and classical mathematical tools, including differential geometry, invariant signatures, and machine learning.
Biography: Peter J. Olver has been on the faculty of the School of Mathematics at the University of Minnesota since 1980, and served as the Head of the Department from 2008 to 2020. He is the author of over 160 published research papers, as well as five books, and is a Fellow of both the American Mathematical Society and SIAM. He has contributed to a wide range of fields, including Lie groups, partial differential equations, the calculus of variations, fluid mechanics, elasticity, quantum mechanics, differential geometry, invariant theory, computer vision, and anthropology.
