The key properties of a useful invariant are that it is computable and distinguishes many different objects. For dynamical systems, an important class of mathematical objects, the construction of invariants can be very involved. Dr. <span>Deeley</span> will use this NSF funding to study invariants of dynamical systems defined via abstract operator algebras and K-theory. The project will also involve significant contributions from early-career researchers, graduate students, and undergraduate students, who will benefit from training through research involvement.</span></div> </div></div> </div> </div> </div> </div> <h2> <div class="paragraph paragraph--type--ucb-related-articles-block paragraph--view-mode--default"> <div>Off</div> </div> </h2> <div>Traditional</div> <div>0</div> <div>On</div> <div>White</div> Fri, 03 Nov 2023 18:15:53 +0000 Anonymous 1115 at /math Meet a Mathematician (MEET) /math/2023/09/05/meet-mathematician-meet <span>Meet a Mathematician (MEET)</span> <span><span>Anonymous (not verified)</span></span> <span><time datetime="2023-09-05T17:09:17-06:00" title="Tuesday, September 5, 2023 - 17:09">Tue, 09/05/2023 - 17:09</time> </span> <div> <div class="imageMediaStyle focal_image_wide"> <img loading="lazy" src="/math/sites/default/files/styles/focal_image_wide/public/article-thumbnail/meet.image_.png?h=0ae9d155&amp;itok=Q6OQcYkF" width="1200" height="600" alt="MEET"> </div> </div> <div role="contentinfo" class="container ucb-article-categories" itemprop="about"> <span class="visually-hidden">Categories:</span> <div class="ucb-article-category-icon" aria-hidden="true"> <i class="fa-solid fa-folder-open"></i> </div> <a href="/math/taxonomy/term/535"> news </a> </div> <div class="ucb-article-content ucb-striped-content"> <div class="container"> <div class="paragraph paragraph--type--article-content paragraph--view-mode--default"> <div class="ucb-article-content-media ucb-article-content-media-above"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="imageMediaStyle large_image_style"> <img loading="lazy" src="/math/sites/default/files/styles/large_image_style/public/article-image/meet.image_.png?itok=e4atp-Z4" width="1500" height="761" alt="MEET"> </div> </div> </div> </div> </div> <div class="ucb-article-text d-flex align-items-center" itemprop="articleBody"> <div><p><i><span><a href="https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.meetamathematician.com%2F&amp;data=05%7C01%7CPeter.Mayr%40Colorado.EDU%7Ca383a7091f254388dc6f08dbae4efa98%7C3ded8b1b070d462982e4c0b019f46057%7C1%7C0%7C638295426458973288%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&amp;sdata=uK109CC9Mxc6ICXIRN%2BdROWL7LcNMUN23MwBeW5SyLw%3D&amp;reserved=0" rel="nofollow" target="_blank">Meet a Mathematician</a></span></i><span> (MEET) is a&nbsp;collection of video interviews with mathematicians from various career stages and diverse backgrounds.

Stange had a surprise discovery; &nbsp;the twenty-year old Local-Global Conjecture for Apollonian circle packings is false! Integer Apollonian circle packings, like the one shown at right, have circles whose curvatures are integers.&nbsp; The image at right colours the circles according to the curvature modulo 3, showing that only integers congruent to 0 or 2 modulo 3 can appear.&nbsp;&nbsp;The conjecture held that, aside from finitely many exceptions and some congruence conditions like the mod 3 restriction in the picture, every sufficiently large integer should appear as a curvature in a primitive integral Apollonian circle packing.&nbsp; The&nbsp;team proved the existence of some new obstructions:&nbsp; for example, some packings cannot admit square curvatures.&nbsp; The proof depends on quadratic and quartic reciprocity.</p> <p>The result was covered in <a href="https://www.quantamagazine.org/two-students-unravel-a-widely-believed-math-conjecture-20230810/" rel="nofollow">Quanta Magazine</a>.</p></div> </div> </div> </div> </div> <div>Summer Haag, Clyde Kertzer, James Rickards and Katherine E.
