András Frank András Frank is a Hungarian mathematician known for contributions to combinatorics, graph theory, and extremal graph theory. He held positions at the Alfréd Rényi Institute of Mathematics and Eötvös Loránd University and collaborated with prominent figures from institutions such as the Institute for Advanced Study, the Mathematical Institute of the Hungarian Academy of Sciences, and international departments at Princeton University, Massachusetts Institute of Technology, and the University of Cambridge. His work intersects with research groups at the University of Szeged, Rutgers University, University of California, Berkeley, and the Courant Institute of Mathematical Sciences.
Frank was born in Budapest and completed secondary studies in a period marked by interactions among institutions like Eötvös Loránd University and the Hungarian Academy of Sciences. He earned his diploma and doctorate at Eötvös Loránd University under advisors from the Alfréd Rényi Institute of Mathematics, connecting to networks including scholars at the Institute for Advanced Study, Université Paris-Sud, and University of Oxford. During his formative years he attended seminars influenced by researchers from Princeton University, Harvard University, Moscow State University, and the Steklov Institute of Mathematics.
Frank's career includes long-term appointments at the Alfréd Rényi Institute of Mathematics and professorship at Eötvös Loránd University. He has been visiting scholar at the Institute for Advanced Study, University of Cambridge, Massachusetts Institute of Technology, Stanford University, University of Chicago, and collaborative stays at the University of Bonn and University of Amsterdam. He served on committees for conferences organized by societies such as the European Mathematical Society, the American Mathematical Society, and the International Mathematical Union. Frank participated in editorial work for journals linked to publishers like Elsevier, Springer-Verlag, and the American Mathematical Society.
Frank made key advances in graph theory and combinatorics, notably on connectivity, matchings, and packing problems, building on foundations laid by researchers like Paul Erdős, László Lovász, András Hajnal, József Beck, and Miklós Simonovits. His results relate to classical problems such as the Erdős–Gallai theorem, Menger's theorem, and the Tutte theorem, and interact with topics treated by mathematicians from Bell Labs, the Courant Institute of Mathematical Sciences, and the Royal Society. Work of Frank connects to algorithms and complexity themes explored at Bell Labs, IBM Research, Microsoft Research, and theoretical results from ACM conferences. Collaborations and citations tie into studies by Noga Alon, Paul Seymour, Robin Thomas (mathematician), László Lovász, and Nikolai Bogolyubov-era combinatorial traditions.
His research includes structural theorems akin to those by Kőnig, Václav Chvátal, and Claude Berge, as well as extremal results in the spirit of Erdős–Gallai and Zoltán Füredi. Frank contributed to packing and covering problems related to works by Jack Edmonds, László Lovász, and Alexander Schrijver, and to connectivity augmentation linked to Mader's theorem and developments by Hendrik Lenstra and William Tutte. These contributions have been applied in networks studied at institutions like Telekom Hungary and in theoretical models referenced by researchers at Bell Labs and AT&T Bell Laboratories.
Frank has received recognition from bodies including the Hungarian Academy of Sciences and has been invited to speak at meetings of the European Mathematical Society and the Joint Mathematics Meetings. He has held visiting fellowships at the Institute for Advanced Study and research grants from agencies such as national councils aligned with the Hungarian National Research, Development and Innovation Office and EU frameworks associated with the European Commission. His professional standing is reflected in memberships and roles within the Hungarian Academy of Sciences and conference committees for venues sponsored by the International Mathematical Union and the American Mathematical Society.
As a professor at Eötvös Loránd University and researcher at the Alfréd Rényi Institute of Mathematics, Frank supervised doctoral students who joined faculties at institutions like the University of Szeged, University of Debrecen, University of Vienna, and international centers such as Princeton University and ETH Zurich. He taught courses informed by traditions from Eötvös Loránd University and research programs connected to Université Paris-Sud and the University of Cambridge, and he contributed to summer schools associated with the European Mathematical Society and the International Mathematical Union.
Frank's personal life intertwines with Budapest's academic community, including associations with colleagues at the Alfréd Rényi Institute of Mathematics, the Hungarian Academy of Sciences, and family ties rooted in institutions like Eötvös Loránd University and cultural centers across Budapest. He has taken part in public lectures and scientific outreach events connected to organizations such as the European Mathematical Society and national museums in Hungary.
