为了加强组合数学与图论研究的学术交流，受全国组合数学与图论学会理事会的委托，全国第五届组合数学与图论大会将于2012年7月15日-7月19日在河南省洛阳师范学院举行，由洛阳师范学院数学科学学院承办。会议宗旨是评述国内外研究动态，交流组合数学与图论及其相关研究领域的研究成果。全国组合数学与图论学会理事长邵嘉裕教授担任本次大会的学术委员会主席。预计将有400多人出席本次会议，其中大会报告人5人（一小时报告）、特邀报告人22人（30分钟），并将有大批研究人员做分组报告。会议议题将包括组合数学及其应用、图论及其应用、理论计算机科学、信息学等多个领域。本项目将面向全国组合数学与图论界的研究人员，并以此促进中国组合数学与图论的研究的繁荣与发展。

In order to enhance the academic communication of Combinatorical Mathematics and Graph Theory (CMGT), the Fifth China National conference on CMGT will be held in Luoyang Normal University from July 15-19, 2012, under the commitment of the CMGT council of China. The purpose of this conference is to commentate domestic and exotic research trends, exchange recent research results on CMGT and its related fields. It is our honor that Jiayu Shao, the Director General of CMGT council of China, will be the organizer of the committee. There will be about 400 attendance, including 5 conference lecturers (1 hour lecture), 22 invited lecturers (30 minutes lecture), and many other scholars will provide group lectures. Conference topics will cover combinatorial mathematics and its applications, graph theory and its applications, and other related fields. This program is open to all demestic researchers in CMGT, we hope it can help to improve the research in these opics and promote our young scholars.
