Cornelius Holland (regicide) Cornelius Holland (regicide) Cornelius Holland (1599 – c. 1671) Born London, England; died possibly at Lausanne, Switzerland about 1671, after he was wanted for his part in the regicide of Charles I of England. Holland is alleged to have been the chief hand in drawing up the charges against King Charles I, although he was not present when the sentence of death was pronounced, nor does his name appear on the warrant of execution. In February 1649, he was appointed to Council of State and was reappointed the next years. Holland lived for a time at Creslow Manor House which
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
