Research output: Contribution to journalArticle


We introduce H-fields as ordered differential fields of a certain kind. Hardy fields extending as well as the field of logarithmic-exponential series over are H-fields. We study Liouville extensions in the category of H-fields as a step towards a model theory of H-fields. The main result is that an H-field has at most two Liouville closures.
