Ulaanbaatar /MONTSAME/ Ninth meeting of Ulaanbaatar Open Mathematics Seminar ran at  Olonlog school last week, gathering scholars from the Mathematics Institute, professors from the Mongolian State University (MSU), the Mongolian State University of Education, and the Mongolian University of Science and Technology, along with teachers of 1st, 11th and Olonlog general education schools.

The keynote presentations were given--"Malfatti’s problem and global optimization” and “Contemporary development of mathematics” by R.Enkhbat DSc, and “Myangat Catalan Number” by MSUE Prof. Dr Ts.Batkhuu.

R.Enkhbat, honorary professor of Irkutsk State University of Russia, consulting professor of Inje University of the Republic of Korea and a professor at the MSU, initiated Mongolia’s hosting of international conference on Optimization. The conferences took place in Mongolia in 2002, 2007, 2010 and 2013, attracting over 300 (overlapped counting) scientists and scholars from 32 countries.

He had reached his goal to solve Malfatti problem using global optimization, and presented his methods, along with some information on contemporary mathematics developments and academic researches by Mongolian mathematicians.

Dr Ts.Batkhuu raised an interesting issue about Catalan numbers. According to historic scientific evidences, it was clear that 18th century Qing-ruled Mongolian mathematician Myangat (known as Minggatu, Mongolian script spelling) used Catalan numbers in his researches before western scientists declared the inventing of it. Moreover, several scientists named Myangat as the founder of Catalan numbers in their scholarly articles, he said. Then, he made a suggestion to call Catalan numbers “Myangat-Catalan numbers”. The seminar participants approved this proposal.
