In this talk, we discuss about graphs with perfect matchings and their relationship with digraphs. Our main focus is on a matching theoretic analogue of the Flat Wall Theorem for bipartite graphs excluding a fixed matching minor. The tight relationship between structural digraph theory and matching theory that allows us to obtain the aforementioned version of Flat Wall Theorem further allow us to deduce a Flat Wall Theorem for digraphs which substantially differs from a previously established directed variant of this theorem.<\/h5>\n<h5>\u00a0<\/h5>\n<h5>Joint work with Sebastian Wiederrecht.<\/h5>\n","protected":false},"excerpt":{"rendered":"<p>Tuesday, Jan 25, 3pm ET (8pm GMT, 9am Wed NZDT)Archontia Giannopoulou, University of AthensA Matching Theoretic Flat Wall Theorem YouTube: https:\/\/youtu.be\/AyHuLUXYrak \u00a0 Abstract: One of the key theorems in Graph Minors is the Flat Wall Theorem which asserts the existence &hellip; <a href=\"https:\/\/matroidunion.org\/?p=4557\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":20,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[11],"class_list":["post-4557","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\/4557","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\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=4557"}],"version-history":[{"count":2,"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/posts\/4557\/revisions"}],"predecessor-version":[{"id":4568,"href":"https:\/\/matroidunion.org\/index.php?rest_route=\/wp\/v2\/posts\/4557\/revisions\/4568"}],"wp:attachment":[{"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=4557"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=4557"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/matroidunion.org\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=4557"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
