[ noun ] (mathematics,logic) a subsidiary proposition that is assumed to be true in order to prove another proposition
Used in print (R. P. Jerrard, "Inscribed squares in plane curves"...)We can now prove several lemmas . The fact that there can not be any limit_points of the set except in closed_intervals follows from the argument used in Lemma 1 , namely , that near any tangent point in the C-plane the curves C and **f are analytic , and therefore the difference between them must be a monotone function in some neighborhood on either side of the tangent point . Now **f and **f must both be tangent points on the nth component in the f-plane ; otherwise by Lemma 1 the component would extend beyond these points . Further , we see by Lemma 2 that the multiplicity of f can only change at a tangent point , and at such a point can only change by an even integer . Related terms |
