It is well known that to a solution of the WDVV equations one can associate a certain function of the infinite number of variables, called the descendent potential. This potential satisfies a system of equations, called the Virasoro constraints, that are described using an infinite sequence of linear differential operators, forming a half of the Virasoro algebra. More recently, a remarkable system of PDEs, extending the WDVV equations, appeared in the context of open Gromov-Witten theory. These new PDEs are called the open WDVV equations. In our joint work with A. Basalaev we construct a descendent potential associated to a solution of the open WDVV equations and
prove an open analog of the Virasoro constraints.
