Two key features in our definition enable this: a) the use of nets instead of sequences, and b) a new concept of completely mixed nets of strategies, drawing on a more detailed interpretation of the notion of a carrier of a strategy.<\/p>\n<p>For finite action sets, our notion of perfect equilibrium coincides with the notion of perfect equilibrium defined by Selten (1975). In the compact-continuous case, our definition yields a nonempty and compact set of perfect equilibria, all of which are weak perfect equilibria in the sense of Simon Stinchcomb (1995). We examine the conditions under which perfect equilibrium meets game-theoretic desiderata such as limit undominatedness and invariance. We provide a variety of examples to motivate our definition, and to illustrate its applicability. Notably, the examples include applications to games with discontinuous payoffs and games played with finitely additive strategies.<\/p>\n<h5>Speaker<\/h5>\n<p><a href=\"https:\/\/www.waseda.jp\/inst\/wias\/other-en\/2024\/11\/13\/17117\/\">VERMEULEN, Dries<\/a><\/p>\n<h5>Co-author<\/h5>\n<p>J\u00e1nos Flesch, Christopher Kops, Anna Zseleva<\/p>\n<h5>Date &amp; Time<\/h5>\n<p>Dec 3, 2024 (Tue.) 17:00 &#8211; 18:30<\/p>\n<h5>Venue<\/h5>\n<p>Building#7\u00a0 Room#209,\u00a0 Waseda Campus, Waseda University<\/p>\n<h5 style=\"text-align: justify;\">Language<\/h5>\n<p>English<\/p>\n<h5>Prospected Audience<\/h5>\n<p>Undergraduate, Graduate, Researchers, Faculty members, general audience<\/p>\n<h5>Co-Organizer<\/h5>\n<p>Waseda Institute for Advanced Studies (WIAS)<\/p>\n<h5>Registration<\/h5>\n<p>Registration is not required to participate.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Visiting Researcher Seminar: A general definition of perfect equilibrium\uff0812\/3\uff09 Details We propose a general de [&hellip;]<\/p>\n","protected":false},"author":6,"featured_media":17110,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[95],"tags":[82,94,73],"class_list":["post-17338","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-en","tag-events-en","tag-general-en","tag-research-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts\/17338","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/comments?post=17338"}],"version-history":[{"count":1,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts\/17338\/revisions"}],"predecessor-version":[{"id":17366,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts\/17338\/revisions\/17366"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/media\/17110"}],"wp:attachment":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/media?parent=17338"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/categories?post=17338"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/tags?post=17338"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
