摘要

<正> In a recent paper the present author has established somerepresentations for a plane curve C in the neighbourhood of a singularpoint O characterized by the property that the tangent t(?) of C at O hasa contact of order m—1((?)2) with the curve.For convenience'sakewe have adopted non-homogeneous coordinates x,y of a point to represent the expansion of the curve.
