2622. Piotr Błaszkiewicz and Piotr Kowalski The class of Krasner hyperfields is not elementary E-mail: Submission date: 22 April 2024 Abstract: We show that the class of Krasner hyperfields is not elementary. To show this, we determine the rational rank of quotients of multiplicative groups in field extensions. Our argument uses Chebotarev's density theorem. We also discuss some related questions.
