                Previous Conference

                The first five conferences in the series were held annually in Phnom Penh, Cambodia, from 2008 until 2012, organized by Dr. Chan Roath, Director of the Department of Scientific Research, Ministry of Education, Youth and Sports, Cambodia, and President of the Cambodian Mathematical Society. The 6th and 7th Conferences were held at Mandalay University, Myanmar, November 1-3, 2013 and November 7-9, 2014, respectively, in cooperation with the American Mathematical Society and the Southeast Asian Mathematical Society. They were chaired by Professor Nyunt Swe, Pro-Rector, Mandalay University of Distance Education.  Yangon University, Yangon, Myanmar, hosted the 8th Conference, which was chaired by Professor Dr. Win Kyi, chair of the Mathematics Department. The 9th and 10th Conferences were held at Mandalay University, Myanmar again in 4-6 November 2016 and November 10-12,2017, respectively. Each of the recent conferences attracted approximately 400 participants from 20 different countries. One exceptionally important outcome of the 6th Conference was the launching of the Mathematical Society of Myanmar on November 3, 2013.
