Abstract
The recent scheme of approximants formed from double power series and proposed by Chisholm (1973) is examined in relation to known functions containing simple singularities of the form (x-xs(y))- gamma , in cases where xs(y) is linear. Attention is focused on the usefulness of these approximants in determining sequences of approximations to the locus of singularities xs(y), and the exponent gamma .Keywords
