Mathematics 555, Fall, 2018 Course Prerequisites
The formal requirement is Math. 455 (numerical analysis, first semester) or
permission of the instructor
and graduate coordinator. The course covers advanced treatment of numerical
methods, analysis of techniques and approximation theory using some basic
real and functional analysis, and some study of algorithms and programming
(currently focusing on using Matlab). Thus, the numerical methods course
(Math. 455 or equivalent), some real analysis, and some programming
experience are helpful. However, if you are missing one of these three
subjects but are proficient in the others, you may be able to focus on what
you hadn't seen during the course and do well. If you have any doubts or
questions, contact me (Ralph Baker
Kearfott).
