Henry Smith (regicide) Restoration in 1660 he was brought to trial for regicide and was sentenced to death. He successfully appealed the sentence which was then commuted to life imprisonment. He was held at the Tower of London until 1664, and was then transported to Jersey where he is thought to have died in 1668 in Mont Orgueil castle. Henry Smith (regicide) Henry Smith (1620–1668) was an English Member of Parliament and one of the regicides of King Charles I. He was born in Withcote, Leicestershire in 1620; son of Henry Smith born in 1589 and Frideswide (Fritzjoyce) Wright. He studied at Oxford
Conformal Killing equation Conformal Killing equation In conformal geometry, the conformal Killing equation on a manifold of space-dimension "n" with metric formula_1 describes those vector fields formula_2 which preserve formula_1 up to scale, i.e. for some function formula_5 (where formula_6 is the Lie derivative). Vector fields that satisfy the conformal Killing equation are exactly those vector fields whose flow preserves the conformal structure of the manifold. The name Killing refers to Wilhelm Killing, who first investigated the Killing equation for vector fields that preserve a Riemannian metric. By taking the trace we find that necessarily formula_7. Therefore we can write the conformal Killing
