Regicide accepted list of what constitutes a regicide. The following is a list of other cases of monarchs in history that have been deliberately killed in some fashion according to recorded history: Note that some of the aforementioned monarchs, such as Nicholas II and Haile Selassie, have already ceased to be rulers at the time of their deaths. Regicide has particular resonance within the concept of the divine right of kings, whereby monarchs were presumed by decision of God to have a divinely anointed authority to rule. As such, an attack on a king by one of his own subjects was
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
