Local multiplicities of tangential trisecants to space curves,erminantal variety in the third symmetric product of the normalization of C..If C possesses cupsps, then there will be an excess component of intersection for last product. We use the set-up from to show how one can find the contribution of cusps to the global number of tangential trisicants.

https://doi.org/10.1007/978-3-031-23926-7s. It is then known that C possesses finitely many tantential trisecants, and that the number of tangential trisecants is 2(d-2)(d-3)+2g(d-6) where d is the degree of C, and g is the geometric genus. The last statement is only correct if one counts tangential trisecants, including flexes, nodes, bit
