## Doowon Koh (고두원) gave a talk on the approach to an upper bound of the point-sphere incidences over the finite field from the restriction estimates for cones at the Discrete Math Seminar

On February 9, 2021, Doowon Koh (고두원) from Chungbuk National University gave a talk at the Discrete Math Seminar on the restriction conjecture for the cone in four dimensions and its applications to the upper bound on the point-sphere incidences in the field field setting. The title of his talk was “On the cone restriction conjecture in four dimensions and applications in incidence geometry“.
