Abstract
For a large class of systems, the interior of the closure of the accessibility set from a point is the interior of this set. As a consequence, equivalent systems, in the Jurdjevic—Kupka's sense, have the same interior and the same boundary for their accessibility sets. This result is used to prove a conjecture of L. R. Hunt.
