Equivariant smoothing conjecture for antisymplectic cusp singularities
Let be a cusp singularity equipped with an antisymplectic involution . Let denote the dual cycle of the cusp. An equivariant smoothing conjecture. Then admits an equivariant smoothing if and only if sits as an anticanonical divisor on a smooth rational surface admitting an antisymplectic involution extending the involution induced on by . This is proposed as an equivariant analogue of Looijenga's smoothability theorem; the necessary and sufficient condition is not proved in general.
