Henry Marten (regicide) Henry Marten (regicide) Henry Marten (1602 – 9 September 1680) was an English lawyer and politician who sat in the House of Commons in two periods between 1640 and 1653. He was an ardent republican and a regicide of King Charles I of England. Marten was the elder son of the successful lawyer and diplomat Sir Henry Marten; his other known siblings were a brother, George Giles Martin, and four sisters, Elizabeth, Jane, Mary, and Agnes .

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
