Such geometric structur es arise naturally in differential and algebraic geometry and\, when they do\, they are often equipped with a conic connection which specifies a dis tinguished family of curves on $M$ in directions of $\\mathcal C$. A class ical example is the null cone bundle of a holomorphic conformal structure equipped with the conic connection induced by the null-geodesics. In a joi nt work with Jun-Muk Hwang we defined an important local invariant for so- called characteristic conic connections\, namely the cubic torsion. In thi s talk I will give a geometric interpretation of the cubic torsion and wil l discuss some applications. This talk is based on a joint work with Andre as Cap.\n LOCATION:https://researchseminars.org/talk/PHK-cohomology-seminar/162/ END:VEVENT END:VCALENDAR
