Hoàng Xuân Sính (born September 8, 1933)[1] is a Vietnamese mathematician, a student of Grothendieck, the first female mathematics professor in Vietnam, the founder of Thang Long University [vi], and a recipient of the Ordre des Palmes Académiques.
She completed a bachelor's degree in 1951 in Hanoi, studying English and French, and then traveled to Paris for a second baccalaureate in mathematics.
[3] Hoàng became the first female mathematics professor in Vietnam[3] and at that time was one of a very small number of mathematicians there with a foreign education.
[4] The French mathematician and pacifist Alexander Grothendieck visited North Vietnam in late 1967, during the Vietnam War, and spent a month teaching mathematics to the Hanoi University mathematics department staff,[5] including Hoàng, who took the notes for the lectures.
[5] She earned her doctorate under Grothendieck's supervision from Paris Diderot University in 1975, with a handwritten thesis.
