We are led to the following problem: to define the functional 7$(a#39;) on T such that M3 = DT;(u) for every ud. (5.1H) We denote by ... _||u-T=vW||2. , . where u an TQ and v^ a#39; is given by (5.78). This function attains its minimum at a#39;yCu) = alt;u, vWagt; /l|v( ^Al2 . (5.113) Let us ... Ill) and (5.116) that T5 (u) = aquot;y (u) for each ueTQ. On the otheranbsp;...
