Time: 2019 Oct 25, 13:30-16:00 Venue: 新斋324, Tsinghua Univ. Speaker: Kevin Kelly (Carnegie Mellon University) Abstract: Inductive knowledge is knowledge that goes beyond the information available.

Speaker: Declan Thompson (Stanford University) Abstract: The comparative expressive power between two logics is generally measured with respect to the existence of a translation from one to the other. A common technique for showing two logics to have different strengths is by demonstration a pair of models […]
Time: 2019 September 27, 13:30-16:00 Venue: 蒙民伟科技大楼南楼S527, Tsinghua Univ. Speaker: Johan van Benthem (Stanford University) Abstract: Dependence is a notion that pervades both ordinary and scientific discourse. We present a decidable base logic of functional dependence whose semantics uses generalized assignment models for first-order logic. This seminar is a survey and crash course in the topic. We determine the structural […]
Time: 2020 April 10-12 Venue: Tsinghua Univ. For more information, see the conference website. Description: Monotonicity, in various forms, is a pervasive phenomenon in logic, linguistics, and related areas. In theoretical linguistics, monotonicity properties (and lattice-theoretic notions such as additivity), as semantic properties of intra-sentential environments, determine the syntactic distribution of a class of terms robustly attested across languages called Negative […]
