Rigidity is a generic property of each fixed graph $G$, in the sense that almost all immersions of $G$ into $\\mathbb{R}^d$ are rigid, or almost all immersions are flexible. The graphs that are generically rigid in $\\mathbb{R}^d$ are the spanning sets of a certain matroid. The main result of my talk will be about rigidity in the plane when the graphs and their immersions have certain symmetry constraints.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Monday, April 19, 3pm ET (8pm BST, 7am Tue NZST)Daniel Bernstein, MITRigidity of symmetry-forced frameworks YouTube:\u00a0https:\/\/youtu.be\/s7U8KrAAKNI Slides: https:\/\/matroidunion.org\/wp-content\/uploads\/2021\/04\/symmForcedRigid.pdf Blog post: https:\/\/matroidunion.org\/?p=3675 \u00a0 Abstract: The fundamental problem in rigidity theory is to determine whether a given immersion of a graph into &hellip; <a href=\"https:\/\/matroidunion.org\/?p=3929\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":19,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[11],"class_list":["post-3929","post","type-post","status-publish","format-standard","hentry","category-matroids","tag-online-talks"],"_links":{"self":[{"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/posts\/3929","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/users\/19"}],"replies":[{"embeddable":true,"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3929"}],"version-history":[{"count":4,"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/posts\/3929\/revisions"}],"predecessor-version":[{"id":3940,"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/posts\/3929\/revisions\/3940"}],"wp:attachment":[{"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3929"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3929"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3929"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
