Given a preference order on a set of possible worlds, there are different ways of extending\/lifting it to a preference order on sets of worlds. For example, A &gt;= B if and only if for all elements b in B there is an element a in A such that a &gt;= b. This way of lifting order is usually named after Lewis, called l-lifting. In this talk, I will focus on another well-known way of order lifting, called &#8220;Egli-Milner ordering&#8221;. Compared with the l-lifting, it only adds one more condition: for all elements a in A there is an element b in B such that a &gt;= b. In this talk, I will examine the resulting logic of the Egli-Milner order. By presenting a sound and complete axiom system, I will show that the Egli-Milner order is &#8220;convex&#8221;, which can be seen as a weaker form of monotonicity. To further illustrate the non-monotonicity of the Egli-Milner order, I will then discuss the relation between l-lifting, Egli-Milner order and conditional belief defined in a plausibility model.<br \/>\n<\/em><\/p>\n<p>See <a href=\"https:\/\/video.uva.nl\/media\/LIRa+seminar+on+2020-05-28+by+Chenwei+Shi\/0_c8rrdpuy\">here<\/a> for the recording of the talk.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Chenwei Shi (Department of Philosophy, Tsinghua University, Beijing)<br \/>\nDate and Time: Thursday, May&nbsp;28th 2020, 16:30-18:00, Amsterdam time.<br \/>\nVenue: online.<br \/>\nTitle: Logic of Convex Order (Joint work with Yang Sun)<\/p>\n<p>Abstract.
