John Fry (regicide) 1657. At the restoration in 1660 he was excluded from the Indemnity and Oblivion Act. Dario Pfanner in the Oxford Dictionary of National Biography states: He is an ancestor of the writer and actor Stephen Fry. John Fry (regicide) John Fry (1609–1657) was a Member of the English Parliament and sat as a Commissioner (Judge) during the trial of King Charles I of England. John Fry, son of William Fry of Iwerne Minster, was born in 1609. He was Member of Parliament for Shaftesbury in the Long and Rump Parliaments, sat through most of the trial of King Charles I,
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
