Mathematical work

Using the LLL-algorithm, Frank, and his student, Éva Tardos developed a general method, which could transform some polynomial-time algorithms into strongly polynomial.[1] He solved the problem of finding the minimum number of edges to be added to a given undirected graph so that in the resulting graph the edge-connectivity between any two vertices u and v is at least a predetermined number f(u,v).[2]

Degrees, awards

He received the Candidate of Mathematical Science degree in 1980, advisor: László Lovász,[3] and the Doctor of Mathematical Science degree (1990) from the Hungarian Academy of Sciences. In 1998 he was an Invited Speaker of the International Congress of Mathematicians in Berlin.[4] He was awarded the Tibor Szele Prize of the János Bolyai Mathematical Society in 2002[5] and the Albert Szent-Györgyi Prize in 2009.[6] In June 2009 the ELTE Mathematical Institute sponsored a workshop in honor of his 60th birthday.[6][7]
