Conference: Contemporary Combinatorics 2011

这次会议的目的是把一群杰出的数学家聚集在一起，他们研究与组合学相关的主题，在最广泛的意义上被理解。特邀演讲者将讨论一系列不同的主题，包括图论、拉姆齐理论、运筹学、理论计算机科学、概率组合学、简单复合体、生物统计学和生物信息学。会议将为来自中南部的数学家提供一个机会，不仅从讲座中受益，而且从与演讲者的个人接触中受益。主讲人是来自康奈尔大学的乔恩·克莱因伯格。作为一名受欢迎的讲师，他在网络方面做了大量工作，尤其以他的HITS算法而闻名，这是一种基于许多商业搜索引擎使用的基于特征向量的方法的网络搜索算法。Kleinberg也因他在小世界实验的算法方面的工作而闻名。在其他荣誉中，他于2005年获得麦克阿瑟基金会奖学金，并于2006年获得奈万林纳奖，该奖项与菲尔兹奖一起每四年颁发一次；这是计算数学中最重要的区别。他的最新著作《网络、人群和市场：关于高度互联世界的推理》于2010年由剑桥大学出版社出版。两场讲座将针对普通观众，孟菲斯地区最好的学校的高中生将被邀请参加。第一节课，乔尔·斯宾塞将会做一个背景演讲，将埃尔多斯定位为20世纪最重要的数学家之一。在第二堂课中，Kleinberg将集中讨论与信息通过网络流动有关的问题，强调人类社会网络中信息流动的数学模型及其在在线世界中的反映。

The aim of this conference is to bring together a group of outstanding mathematicians who work on topics related to combinatorics, understood in the widest sense. Invited speakers will address a diverse set of topics including graph theory, Ramsey theory, operation research, theoretical computer science, probabilistic combinatorics, simplicial complexes, biostatistics and bioinformatics. The meeting will provide an opportunity for mathematicians from the Mid-South to benefit not only from the lectures but also from personal contacts with the speakers. The main speaker is Jon Kleinberg from Cornell University. A popular lecturer, he has done great work on networks and is particularly well known for his HITS algorithm, an algorithm for web search that builds on the eigenvector-based methods used by many commercial search engines. Kleinberg is also known for his work on algorithmic aspects of the small world experiment. Among other honors, he received a MacArthur Foundation Fellowship in 2005 and the Nevanlinna Prize in 2006, an award that is given out once every four years along with the Fields Medal; it is the premier distinction in Computational Mathematics. His most recent book, entitled Networks, Crowds, and Markets: Reasoning About a Highly Connected World, was published by Cambridge University Press in 2010.Two lectures will be aimed at a general audience and high school students from the best schools in the Memphis area will be invited to attend. In the first lecture, Joel Spencer will give a contextual talk positioning Erdos as one of the most significant mathematicians of the 20th century. In the second lecture, Kleinberg will focus on questions related to flow of information through networks, emphasizing mathematical models for information flow in human social networks and their reflections in the on-line world.
