C. DUNHAM Department of Computer Science The University of Western Ontario will speak on DIFFICULTIES IN RATIONAL CHEBYSHEV APPROXIMATION A B S T R A C T In uniform approximation by (ordinary or generalized) rational Function p/q, where the only restraint on denominator q is that q > 0, we have two sources of difficulty, degeneracy and small denominators. The problem they cause are numerous: some are well known but others have not been studied. A class of potential cures for the difficulties is proposed.
