If you have a question about this talk, please contact nobody. TWTW01 - Twistors in Geometry & Physics We explain the notion of a cone structure with a characteristic conic connection, which arises from the theory of minimal rational curves in algebraic geometry. We study the relation between torsion tensors of principal connections on G-structures and characteristic conic connections on associated cone structures. We formulate a sufficient condition under which the existence of a characteristic conic connection implies the existence of a torsion-free principal connection. This sufficient condition holds for adjoint representations of simple Lie algebras different from type A or C. This is a joint work with Qifeng Li.
