摘要

A two-sided Bargmann space is defined to extend the notion of the quaternionic Bargmann space of slice regular functions to \({\mathbb {H}}^2 \) H 2 . A systematic study is presented and includes a precise description of its middle hilbertian structure, its two-sided orthogonal basis, related reproducing kernel and its integral representation by a two-sided Bargmann type transform.
