讲座题目:“Workshop on Order, Topology and Logic”系列学术报告
讲座人: 赖洪亮 教授等
讲座时间:9:00
讲座日期:2018-4-14
地点:数学与信息科学学院学术报告厅

讲座题目1:Regularity vs. constructive complete (co) distributivity
讲座时间:9:00-10:00
讲座日期:2018-4-14
报告人:赖洪亮 教授
讲座内容简介:It is well known that a relation ϕ between sets is regular if and only if Kϕ is completely distributive(cd), where Kϕ is the complete  lattice consisting of fixed points of the Kan adjunction induced by ϕ. For a small quantaloid Q, we investigate the Q-enriched version of this classical result, i.e., the regularityof Q-distributors versus the constructive complete distributivity (ccd) of Q-categories, and prove that “the dual of Kϕ is (ccd) ⇒ ϕ is regular ⇒ Kϕ is (ccd)” for any Q-distributor ϕ. Although the converse implications do not hold in general, in the case that Q is a commutative integral quantale, we show that these three statements are equivalent for any ϕ if and only if Q is a Girard quantale.

讲座题目2:On fuzzy differentiability of fuzzy-number-valued functions
讲座时间:10:00-11:00
讲座日期:2018-4-14
报告人:邱东 教授
讲座内容简介:
The importance of the derivative of a function in the study of analysis is well-known. For fuzzy functions, the Hukuhara difference and its generalized differences are used to define the differentiability. These generalized derivatives are motivated by their usefulness in a very quickly developing area at the intersection of set-valued analysis and fuzzy sets, namely, the area of fuzzy analysis and fuzzy differential equations. But in many applications they appear to have own imperfections and to be very restrictive. 
In this talk, on the one hand, I will give an improved characterization for the g-derivative which is the most general of those existing generalized H-derivatives. On the other hand, I will define the differentiability from a totally new point of view. I also show connections to the ideas of generalized H-derivatives. Finally, some potential applications will be discussed.

讲座题目5:Diagonals between distance distributions
讲座时间:15:30-16:30
讲座日期:2018-4-14
报告人:申力立 博士
讲座内容简介:The quantale of distance distributions is of fundamental importance for understanding probabilistic metric spaces as enriched categories. Motivated by the categorical interpretation of partial metric spaces, we are led to investigate the quantaloid of diagonals between distance distributions, which is expected to establish the categorical foundation of probabilistic partial metric spaces. Observing that the quantale of distance distributions w.r.t. an arbitrary continuous t-norm is non-divisible, we precisely characterize diagonals between distance distributions, and prove that one-step functions are the only distance distributions on which the set of diagonals coincides with the generated down set.

讲座题目6:Weak algebraic information systems and a new equivalent category of DOM of domains
讲座时间:16:30-17:30
讲座日期:2018-4-14
报告人:何青玉 博士
讲座内容简介:In this topic, concepts of generalized algebraic information system (in short, GA-inf) and weak algebraic information system (in short, wA-inf) are introduced. Relationships among several algebraicities of information systems are explored. Main results are:
(1) A dcpo D is an algebraic domain iff D is represented by an algebraic information system (in short, A-inf), and iff D is represented by a GA-inf;
(2) every A-inf is a GA-inf and a wA-inf;
(3) every C-inf S(D, B) induced by a domain with a basis B is a wA-inf;
(4) the category WAINF of wA-infs and approximable mappings is equivalent to the category DOM of domains and Scott continuous functions.

讲座题目7:Some research progress on (L,M)-fuzzy convergence theory
讲座时间:9:15-10:15
讲座日期:2018-4-15
报告人:庞斌 博士
讲座内容简介:With the development of fuzzy topology, various types of fuzzy convergence structures have been investigated in different frameworks of fuzzy topological spaces. In this talk, we mainly focus on three types of fuzzy convergence structures in the framework of (L,M)-fuzzy topological spaces, including stratified (L,M)-fuzzy Q-convergence structures, enriched (L,M)-fuzzy convergence structures and stratified (L,M)-ordered convergence structures. Generally, we call them (L,M)-fuzzy convergence structures. Concretely, we will study their Cartesian-closedness and their categorical relations with stratified (L,M)-fuzzy topological spaces.
