John Bourchier (regicide) King Henry VIII; Charles I was a great-great-grandson of Margaret Tudor-a sister of King Henry VIII. He was the great-great-great-grandson of Richard Neville, 16th Earl of Warwick, who was known as the "Kingmaker" for helping to place both Edward IV and Henry VI upon the throne during the War of the Roses. John Bourchier (regicide) Sir John Bourchier or Bourcher (c. 1595 – August 1660) was an English parliamentarian, Puritan and one of the regicides of King Charles I. John Bourchier was the son of William Bourchier of Beningbrough and grandson of Sir Ralph Bourchier. He was probably educated at
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
