Abstract
A number field is called primitive if and are the only subfields of . Let be a nice curve over of genus . A point of degree on is called primitive if the field of definition of the point is primitive. In this short note we prove that if has a divisor of degree , then has infinitely many primitive points of degree . This complements the results of Khawaja and Siksek that show that points of low degree are not primitive under certain conditions.
