This page contains information for the Spring 2003 version of this math course. B B Check out the Announcement for the course which will take place MWF 13:16-14:10 at B231 Van Vleck.
As promised in the Announcement, there will be some HOMEWORK ASSIGNMENTS , and the same page now also provides answers to all the assignments.
For an earlier version of this course, Amos Ron, a co-instructor then for the second part, prepared the following notes . I will use these notes for the last part of the present course but will not be able to resist the temptation to make changes; so, have a look at the emended(?) notes. In addition, that page (as of 23feb98) also contains an alternative way of looking at approximation order by convolution kernels.
There is a 100-page survey, meant for a general audience, of NONLINEAR APPROXIMATION by Ron DeVore, that has appeared in Acta Numerica; 7; 1998.
