## Complex Analysis Research Unit (CARU)

Complex Analysis is an active and classical area of Mathematics, its roots go back to the 18th century. As such, it is deeply interconnected with other areas of Analysis, with Topology, Algebraic Geometry, Differential Geometry and Partial Differential Equations. More recently, this area has also been noticed by a wider public through developments in Complex Dynamics and the captivating pictures of fractals that result from the study of Complex Dynamics. Complex Analysis also finds applications in Analytic Number Theory and in Physics, for example in classical Hydrodynamics and in Quantum Field Theory.

The *Complex Analysis Research Unit* from the American University of Beirut focuses on the geometric aspects of Complex Analysis while emphasizing its connections to Algebraic Geometry, Differential Geometry and Partial Differential Equations.

The unit is established under the Center for Advanced Mathematical Sciences (CAMS) at the American University of Beirut, with founding members who have benefited from CAMS support over the last decade, advancing the Center's mission through international collaborations and events involving the local mathematical community.
