报告题目:Euler Numbers and Polynomials Associated with Zeta Function

报告人:Taekyun Kim教授

日期和时间:20161217日(周六)上午9:00

报告地点:理学院楼四层B403

报告人简介:Taekyun Kim教授现任韩国首尔光云大学数学系教授,博士毕业于日本九州大学。目前主要从事解析数论、解析组合论和Umbral Calculus的研究,已发表论文500多篇,其中被SCI收录180多篇。主编两家被Scopus索引的数学杂志。20155月获得韩国国家最高科学技术奖。

报告摘要:In this lecture, the speaker introduces some properties and identities of the Euler numbers and polynomials arising from Fourier series. In addition, he gives some applications of these identities and studies the evaluation of the Zeta functions at positive integers.


学术报告二

报告题目:Degenerate Changhee Polynomials and Numbers

报告人:Seog-Hoon Rim教授

日期和时间:20161217日(周六)上午10:00

报告地点:理学院楼四层B403

报告人简介:Seog-Hoon Rim教授现任职于韩国庆北国立大学,博士毕业于美国威斯康辛大学,主要从事解析数论和Umbral Calculus的研究,已发表学术论文150多篇,其中被SCI收录60多篇。目前Rim教授还任韩国章田数学会理事长、韩国庆北国立大学学术委员会主任和图书馆馆长。

报告摘要:In this talk, the speaker considers a new family of polynomials which are called the degenerate modied q-Euler polynomials, gives some interesting identities which come from the symmetric group of degree n, and investigates identities for such polynomials from the fermionic p-adic integral onZp.


学术报告三

报告题目:Similarity Measures for Fuzzy Sets on the Fuzzy Measure

报告人:Sanghyuk Lee教授

日期和时间:20161217日(周六)上午11:00

报告地点:理学院楼四层B403

报告人简介:Sanghyuk Lee received Doctorate degree from Seoul National University, Seoul, Korea, in Electrical Engineering in 1998. His main research interests include data evaluation with similarity measure, human signal analysis, high dimensional data analysis, controller design for linear/nonlinear system, and observer design for linear/nonlinear system. Dr. Lee is currently working as an Associate Professor at the Department of Electrical and Electronic Engineering of Xi’an Jiaotong-Liverpool University (XJTLU), Suzhou, China, which he joined in 2011. He has also been working as a founding director of the Centre for Smart Grid and Information Convergence (CeSGIC) in XJTLU since 2014. He hasbeen servingas a Vice President of Korean Convergence Society (KCS) since 2012, and was appointed as an Adjunct Professor at Chiang Mai University in 2016, Chiang Mai, Thailand. Dr. Leeorganized several international conferences with KCS and was awarded multiple honors such as outstanding scholar/best paper award from KCS and Korean Fuzzy Society.

报告摘要:Measures of similarity between data is rational background to pattern recognition, decision theory, and other related fields. In this talk, the speaker illustrates notations and definitions to explain similarity measure and proposes similarity measures on discrete fuzzy sets and uncountable fuzzy sets. By comparison with measure on two kinds of similarity measure, the speaker has notified that two similarity measures have similar formation. However, there is a big difference actually. With the help of fuzzy measure, the speaker derived similarity measure on uncountable sets. With artificial data distribution, the speaker verified the proposed measure usefulness.
