β¦ Synopsis
We study the strong continuity of the map u ~-+ (b.u, b.u(I u > u(.)l) ). Here, b.u = -~a ,w(a) = .f{u>u.(a)} +fo-JU>u*(a)l(bl{ .... (a)}).(r) dT for a El0, means g~[, u. (respectively, (bl{u=u.(a)}).) denotes the decreasing rearrangement of u (respectively b restricted to the set {u -u.(a)}) and IEI denotes the Lebesgue measure of a set E included in a domain ft. The results are useful for solving plasmas physics equations or any nonlocal problems involving the monotone rearrangement, its inverse or its derivatives. Keywords--Relative rearrangement, Monotone rearrangement, Galerkin method. MAIN RESULTS If we want to solve the problem: find u in H~(~) (~ open bounded set of R N) satisfying -Au = g(u~.(I u > u(x)l), b.u(lu > u(x)l)) + f(x) and use a Galerkin approximation then we will be led to consider a sequence of finite dimension spaces Vm and solve: find Um C Vm, [Turn ;Β’] = 0,

The Lippmann-Schwinger equation for the reactance operator is converted into a system of linear equations. By using spline functions the principal-value singularity of the integral kernel can be treated analytically. Throughout this work recurrence relations suitable for automatic computation are de
The authors regret that the above-referenced paper contains a number of misprints. In the statement of Theorem 3.1 (Eq. (3.1)) the condition C n+1 is incorrect. In fact, the set C n+1 in Theorem 3.1 should be replaced by the following one: The proof on page 15 line 5 should be inserted with the fol
