Abstract:$ \mathbb C $-convexity of the closure, interiors and their lineal convexity are considered for $ \mathbb C $-convex sets under additional conditions of boundedness and nonempty interiors. The following questions on closure and the interior of $\mathbb C $-convex sets were tackled
The closure of a bounded $ \mathbb C $-convex domain may not be lineally-convex.
The closure of a non-empty interior of a $ \mathbb C $-convex compact in $ \mathbb C^n $ may not coincide with the original compact.
The interior of the closure of a bounded $ \mathbb C $-convex domain always coincides with the domain itself.
The questions were formulated by Yu. B. Zelinsky.
Keywords:strong linear convexity, $ \mathbb C $-convexity, projective convexity, lineal convexity, Fantappie transform, Aizenberg–Martineau duality.
