American Univesity of Beirut

Number Theory Research Unit

​​​​​​​​​​The Number Theory Research Unit (NTRU) brings together AUB number theorists, their students, and collaborators with the aim of strengthening research and teaching in number theory, and fostering regional collaborations at the service of the field. The unit is established under the Center for Advanced Mathematical Sciences (CAMS) at the American University of Beirut, with founding members who between them have benefited from CAMS support for more than two decades now, advancing the Center's mission through international collaborations and associated activities​, all the while rooting their respective research programs at AUB.

NTRU will focus on current research topics in number theory and modular forms. Unit members will host specialists in their respective research areas, organizing extended thematic programs, workshops and international conferences. Number theorists in the region will be invited to join the Unit's efforts, stimulating interest in number theory in general and sustaining focused research in fields of mutual interest. The Unit will partner with international programs to strengthen its local projects, expand its network of associated scholars, and work to secure extramural funds for collaborative projects. In due course, the Unit will, in collaboration with CAMS, announce openings for postdoctoral positions.
