Abstract
Let be a curve defined over a number field . We say a closed point of degree is isolated if it does not belong to an infinite family of degree points parametrized by the projective line or a positive rank abelian subvariety of the curve's Jacobian. Building on work of Bourdon, Ejder, Liu, Odumodu, and Viray, we characterize elliptic curves with rational -invariant which give rise to an isolated point of odd degree on for some positive integer .
