The boundary of a convex set is always a convex curve. The intersection of all convex sets containing a given subset A of Euclidean space is called the convex hull of A. It is the smallest convex set containing A.
Rector (ecclesiastical) A rector is, in an ecclesiastical sense, a cleric who functions as an administrative leader in some Christian denominations, and in Islam. In contrast, a vicar is also a cleric but functions as an assistant and representative of an administrative leader.
Where people own property within land that was once rectorial (part of a rectory or glebe), they may have unwittingly inherited a responsibility to fund repairs to the chancel of the medieval-founded Church of England parish church or Church in Wales church which that glebe land supported.he Government has, however, acted to make the existence of the liability much simpler to discover. From October 2013, chancel repair liability will only bind buyers of registered land if it is referred to on the land register.
