S. Chern in 1981 gave a geometric interpretation of solutions to the Sine-Gordon equation, that is the pseudosphere. This relates partial differential equations and differential geometry. Such a relation gives rise to the study of integrable systems and geometries. In this talk, we will recall the history of the Sine-Gordon equation and the pseudosphere at first. Then we will introduce some related and generalized questions with the known results. In the end, we will introduce our recent results on U-NLS, Schr\\&#8221;odinger flows and Heisenberg groups in this direction.<\/p>\n<p>Time: Nov. 17 (Wed.), 2:00 p.m., 2021<br \/>\nPlace: Room 212, Department of Mathematics, NTNU<br \/>\nTea Time: Nov. 17 (Wed.), 1:30 p.m., 2021<br \/>\nTea Place: Room 104, Department of Mathematics, NTNU<\/p>\n<p>URL of class\uff1a<span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" href=\"https:\/\/meet.google.com\/ngz-pnbq-ghg\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/meet.google.com\/ngz-pnbq-ghg<\/a><\/span><br \/>\nPlease log in with your school google account.\u3000(<a href=\"https:\/\/gapps.ntnu.edu.tw\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"color: #ff0000;\">https:\/\/gapps.ntnu.edu.tw<\/span><\/a>)<\/p>\n<p class=\"wpf_wrapper\"><a class=\"print_link\" href=\"\" target=\"_blank\">\u53cb\u5584\u5217\u5370<\/a><\/p><!-- .wpf_wrapper -->","protected":false},"excerpt":{"rendered":"<p>Speaker\uff1a\u5289\u7b71\u51e1\u6559\u6388 Job title\uff1a\u6de1\u6c5f\u5927\u5b78\u6578\u5b78\u7cfb Title: Geometric Method [&hellip;]<\/p>\n","protected":false},"author":18,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[1,18,122,124],"tags":[],"_links":{"self":[{"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/posts\/11571"}],"collection":[{"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/users\/18"}],"replies":[{"embeddable":true,"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/comments?post=11571"}],"version-history":[{"count":4,"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/posts\/11571\/revisions"}],"predecessor-version":[{"id":11872,"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/posts\/11571\/revisions\/11872"}],"wp:attachment":[{"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/media?parent=11571"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/categories?post=11571"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/virtual.math.ntnu.edu.tw\/index.php\/wp-json\/wp\/v2\/tags?post=11571"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
