Abstract
Local Pl\"ucker formulas relate the vector of metrics on a holomorphic curve in the projective space, induced by the Fubini-Study metrics on projetive spaces via Pl\"ucker embeddings of associated curves, to the corresponding vector of curvatures. Givental noted that the vector of curvatures is expressed in terms of the vector of metrics via Cartan matrix of type and extended this observation from type to all nonexceptional types. In this paper we show how local Pl\"ucker formulas for special orthogonal groups, i.e. for Cartan matrices of type and , can be obtained by reduction to the classical case.
