Abstract
We study the local symplectic algebra of curves. We use the method of algebraic restrictions to classify symplectic singularities. We define discrete symplectic invariants - the Lagrangian tangency orders. We use these invariants to distinguish symplectic singularities of classical singularities of planar curves, singularity and singularity. We also give the geometric description of these symplectic singularities.
