Symplectic singularity of curves with semigroups (4,5,6,7), (4,5,6) and (4,5,7)

Fausto Assunção de Brito Lira, Wojciech Domitrz, Roberta Wik Atique

We study the local symplectic algebra of curves with semigroups $(4,5,6,7)$, $(4,5,6)$ and $(4,5,7)$. We use the method of algebraic restrictions to parameterized curves as in \cit…
