Title: A characterization of the family of secant lines to a hyperbolic quadric in $PG(3,q)$, $q$ odd
In this talk, we shall discuss a combinatorial characterization of the family of secant lines of the 3-dimensional projective space $PG(3,q)$ which meet a hyperbolic quadric in two points (the so called secant lines) using their intersection properties with points and planes. This is joint work with Puspendu Pradhan.
