Jana Semrau<p>Many congratulations to Susanna Heikkilä from the University of Helsinki 💐👏🏻</p><p>She "has made a significant breakthrough in topology, a branch of mathematics concerned with the properties and shapes of geometric surfaces. One of the articles from her doctoral thesis has been accepted for publication in the Annals of Mathematics, one of the most prestigious journals in the field. [...]<br>The main result of my doctoral thesis complements the answer to Gromov’s question, as the result can be used to classify closed simply connected four-dimensional manifolds for which there is a quasiregular mapping from a Euclidean space,” says Postdoctoral Researcher Susanna Heikkilä.""</p><p><a href="https://mastodon.social/@ScienceScholar/114211601295086711" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">mastodon.social/@ScienceSchola</span><span class="invisible">r/114211601295086711</span></a></p><p>Via <span class="h-card" translate="no"><a href="https://mastodon.social/@ScienceScholar" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>ScienceScholar</span></a></span></p><p><a href="https://fediscience.org/tags/BranchedCovers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>BranchedCovers</span></a> <a href="https://fediscience.org/tags/ExteriorAlgebra" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ExteriorAlgebra</span></a> <a href="https://fediscience.org/tags/MontelsTheorem" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MontelsTheorem</span></a> <a href="https://fediscience.org/tags/QuasiregularEllipticity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>QuasiregularEllipticity</span></a> <a href="https://fediscience.org/tags/QuasiregularMappings" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>QuasiregularMappings</span></a> <a href="https://fediscience.org/tags/Mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mathematics</span></a> <a href="https://fediscience.org/tags/Topology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Topology</span></a> <a href="https://fediscience.org/tags/Breakthrough" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Breakthrough</span></a></p>
