Prof. Le Van Thiem is the founder of the modern mathematics in Vietnam. Born in Duc Tho district, Ha Tinh province in 1918, with his excellent academic achievements, he was awarded a scholarship to study in France. In 1939 he went to Paris to study mathematics. He defended his doctoral dissertation at the University of Göttingen (Germany) in 1945, with the theme "Über die Bestimmung des Typus einfach zusammenhängender offener Riemannscher Flächen". He was the first Vietnamese mathematician to have an international publication. He defended the National Doctorate in France in 1949 with his dissertation "Sur le problème d"inversion dans la théorie de la distribution des valeurs des fonctions méromorphes". He had time working with Prof. Rolf Herman Nevanlinna at the University of Zurich, Switzerland, until 1949.

In 1949, in response to the appeal by President Ho Chi Minh, Prof. Le Van Thiem abandoned his scientific position in Zurich to return to active participate in the struggle for national independence. In 1951, Le Van Thiem was moved by the Government from the southern region to Viet Bac with the task of building the University of Basic Science (now the Hanoi University of Science) and the University of Advanced Education (now the Hanoi National University of Education). He was appointed rector of the two universities where he taught theoretical mechanics. He was the first Head of the Institute of Mathematics, the first President of the Vietnam Mathematical Association and the first editor-in-chief of the two Vietnamese mathematical journals, "Acta Mathematica Vietnamica" and "Vietnam Journal of Mathematics". He led the Institute of Mathematics for 15 years. Although he was busy with many administrative activities, he continued to study and teach mathematics. He led many mathematicians in the field of complex analytics, complex geometry, Nevanlinna Theory in Vietnam. The descendants in these fields are Prof. Ha Huy Khoai, Nguyen Van Khue, Do Duc Thai, Ta Thi Hoai An, Tran Van Tan, Nguyen Quang Dieu, Pham Hoang Hiep and many modern Vietnamese mathematicians.

Attendants at the opening ceremony were representatives of organizing agencies and sponsors, many Vietnamese and foreign mathematicians. Speaking at the opening ceremony, on behalf of the leaders of the Vietnam Academy of Science and Technology, Prof. Nguyen Dinh Cong, VAST Vice President, welcomed domestic and foreign delegates to the conference, stressing that Prof. Le Van Thiem is one of the scientists of the first generation of modern scientists in Vietnam, who made great contributions to the development of the educational and scientific system since national independence in the mid-twentieth century. For the Vietnam Academy of Science and Technology, Prof. Le Van Thiem was the founder and head of the Institute of Mathematics - one of the first few specialized institutes of the academy. During this international conference, presenters were mathematicians coming from many countries around the world, including famous mathematicians. Prof. Nguyen Dinh Cong expressed his belief that the conference would be a bridge between Vietnamese mathematicians and international mathematicians in the field of complex analytics, complex geometry, Nevanlinna Theory, digital theory and other topics in mathematics. He expressed his thanks to the delegates for their presence and wished the conference success.
