We show the four-dimensional Newton's constant obtained naturally from five-dimensional brane world with a tinily sloping extra dimension, which is independent of the bulk Weyl tensor. The corresponding universe is stiff fluid dominated when the slope of extra dimension is very small. Otherwise, the universe may be undergoing a self-acceleration at present epoch and have a decelerated phase in very recent past.

Quasi-Newton methods are applied to solve interface problems which arise from domain decomposition methods. These interface problems are usually sparse systems of linear or nonlinear equations. We are interested in applying these methods to systems of linear equations where we are not able or willing to calculate the Jacobian matrices as well as to systems of nonlinear equations resulting from nonlinear elliptic problems in the context of domain decomposition. Suitability for parallel implementation of these algorithms on coarse-grained parallel computers is discussed.

Christopher Newton was born in England in June of 1936. He received his education at Sir Roger Manwood’s School in Kent, the University of Leeds, Purdue University in Indiana and the University of Illinois where he received his M.A. He founded Theatre Calgary in 1968 and was the artistic director there until 1971. He was appointed as the artistic director of the Vancouver Playhouse where he established the Playhouse Acting School with Powys Thomas. Mr. Newton has also performed and directed at Stratford Festivals and on Broadway. He became the artistic director at Shaw Festival in Niagara-on-the-Lake in 1979 and remained there for 23 seasons until 2002. Mr. Newton has many television, radio and film credits to his name as well as having written many stage plays. Mr. Newton has received honorary degrees from Brock University (1986), the University of Guelph (1989), Wilfrid Laurier University (1997) and Buffalo State University. He was made an Honorary Fellow at the Royal Conservatory of Music of Toronto (1993) and of Ryerson Polytechnic University (1995). He has won the Governor General’s performing arts award (2000), the Molson Prize and the Thomas DeGaetani Award from the United States Institute for Theatre Technology. In 1996 he was made an Honorary Life Member of the Association for Canadian Theatre Research and in the same year he received the M. Joan Chalmers Award for Artistic Direction. In 1995, he was made a Member of the Order of Canada and he won a Governor General's Performing Arts Award in 2000. Christopher Newton is currently the Artistic Director Emeritus at the Shaw Festival.

The application of nonlinear schemes like dual time stepping as preconditioners in matrix-free Newton-Krylov-solvers is considered and analyzed. We provide a novel formulation of the left preconditioned operator that says it is in fact linear in the matrix-free sense, but changes the Newton scheme. This allows to get some insight in the convergence properties of these schemes which are demonstrated through numerical results.
