David Hockney the Order of Merit, an honour restricted to 24 members at any one time for their contributions to the arts and sciences. He was a Distinguished Honoree of the National Arts Association, Los Angeles, in 1991 and received the First Annual Award of Achievement from the Archives of American Art, Los Angeles, in 1993. He was appointed to the Board of Trustees of the American Associates of the Royal Academy Trust, New York in 1992 and was given a Foreign Honorary Membership to the American Academy of Arts and Sciences, Cambridge, Massachusetts in 1997. In 2003, Hockney was awarded the
Restricted Lie algebra Restricted Lie algebra In mathematics, a restricted Lie algebra is a Lie algebra together with an additional ""p" operation." Let "L" be a Lie algebra over a field "k" of characteristic "p>0". A "p" operation on "L" is a map formula_1 satisfying If the characteristic of "k" is 0, then "L" is a restricted Lie algebra where the "p" operation is the identity map. For any associative algebra "A" defined over a field of characteristic "p", the bracket operation formula_11 and "p" operation formula_12 make "A" into a restricted Lie algebra formula_13. Let "G" be an algebraic group over a
